A 2.75 kg block is pulled across a flat, frictionless floor with a 5.11 N force directed 53.8° above horizontal. What is the total force acting on the block? (total force = N)
Answer:
F = 3.01 N
Explanation:
Given that,
Mass of a block, m = 2.75 kg
Force applied to the block, F = 5.11 N
It is directed 53.8° above horizontal.
We need to find the total force acting on the block. The force acting on it is given by :
[tex]F=F\cos\theta\\\\F=5.11\times \cos53.8\\F=3.01\ N[/tex]
So, 3.01 N of force is acting on the block.
3.01 works as the right answer

what is moon rotation ?The moon is the captivating celestial body that can be observed through eyes, it is the biggest heavenly body in the night sky which changes its shape constantly.
The waning and waxing of moon cause the changes in face of the moon. The waning and waxing of the moon is directly related to the rotation of the moon.
The rotation of the moon is an extraordinary occurrence as the time the moon takes for completely orbiting the earth is exactly the time it takes to rotate once on its own axis.
Both the actions take 27.3 days to complete. This is unique feature of the moon is rare when compared to other celestial bodies. The energy given to the moon comes from Earth's rotation and to compensate, our planet is slowing down.

a body of mass 10kg moving with a velocity 4m/s strikes a vertical wall horizontally and returns back with same velocity. find the impulse exerted on the wall if the time of contact is 0.02s
Answer:
1.96Ns
Explanation:
Impulse = Ft = m(v-u)
Impulse = Force * time
Impulse = mgt
Impulse = 10 * 9.8 * 0.02
Impulse = 98*0.02
Impulse = 1.98Ns
Hence the impulse exerted is 1.96Ns

A boy of mass, m weights 895 N. What is his mass, m?
a) 895 kg
b) 8.95 kg
c) 89.5 kg
d) None of the above
Answer:
One: either C or D. I can't give you a definite answer. See below.
Two: D
Explanation:
One
F = m * a
F = 895 N
a = 9.8
m = F/a
m = 895/9.8
m = 91.82
This turned out to be a very nasty little question. I don't know how you should answer it. The closest answer is C but is it close enough? You have to decide if you've had approximation questions before. If you have, C is the answer. If not then D is what you should choose.

A boy of mass, m weights 895 N. What is his mass, m?
Answer:
91.3 kg
Explanation:
weight = m*g
m: mass
g: gravity = 9.8 or 10 (depends on what your instructor tells you to use)
mass = w/g
895/9.8 = 91.3 KG
What is the relationship between the mass of the objects and the force exerted?
Answer:
Objects with mass exert forces on each other via the force of gravity. This force is proportional to the mass of the two interacting objects, and is inversely proportional to the square of the distance between them. The factors G, M, and r are the same for all masses at the surface of the Earth.
In the following graph , what is the object’s average velocity?
Answer:
according to the graph, vavg= Stotal/Ttotal =10
Which has more momentum a 100 kg kid riding a bike 10m/s or a 5000 kg truck barley rolling at 0.1 m/s
Answer:
The momentum of bike is more.
Explanation:
Given that,
Mass of the kid, m = 100 kg
Speed of the bike, v = 10 m/s
The momentum of the kid is given by :
p = mv
So,
p = 100 kg × 10 m/s
p = 1000 kg-m/s
Mass of the truck, m = 5000 kg
Speed of the truck, v = 0.1 m/s
The momentum of the truck is given by :
p = 5000 kg × 0.1 m/s
= 500 kg-m/s
So, the momentum of the kid riding a bike is more than that of the truck.

A car is travelling to the right with a speed of 40 m/s when the driver slams on the brakes. The car skids for 4 s with constant acceleration before it comes to a stop. What was the rate of the car's acceleration as it skidded to a stop?
Answer:
10m/s^2
Explanation:
Given data
velocity= 40m/s
time= 4 seconds
Acceleration a =????
We know that
a= velocity/time
substitute
a=40/4
a= 10m/s^2
Hence the acceleration will be 10m/s^2
The mass of the motorbike and rider is 286 kg. Calculate the acceleration of the motorbike at this moment in time.
Answer:
[tex]a=4.03\ m/s^2[/tex]
Explanation:
Given that,
The mass of the motorbike and rider is 286 kg.
We need to find the acceleration of the motorbike at this moment in time.
Net force acting on the bike is given by :
F = 2000 N - 845 N = 1155 N
Let a be the acceleration of the motorbike. So,
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{1155}{286}\\\\a=4.03\ m/s^2[/tex]
So, the acceleration of the motorbike is [tex]4.03\ m/s^2[/tex].
