Freud was an influential and controversial psychologist who believed that psychology should study the unconscious mind. Describe
the two books Freud published in the early 1900s. (Site 2)
Answers
Answer:
The Interpretation of Dreams": Freud noticed that dreams played an important role in his analysis of neurotic and "hysterical" patients. When he asked his patients to talk about whatever came into their minds, they often referred to their dreams, which would set off other associations and often illuminate other important connections in their past experience. It took Freud about two years to write the book, finishing it in September 1897.

A footballer applies a force of 30.0N, for a period of 0.05s, if the mass of the ball is 0.075kg, calculate the speed which half of the ball moves
Answers
By formula: F= m(v-u)/T
Givens m=0.075kg
u=0
T=0.05s
F=30.0N
=> 30.0=0.075(v-0)/0.05
v=20.00m/s^-1
In a friendly soccer game, you hit a ball with a speed of 13 m/s at an angle of 24 degrees above the horizontal. (A) How long does it take for the ball to reach the goal if it is 4.2 meters away? (B) How high is the ball when it reaches the goal?
Answers
a) V= 13m/s at 24 degrees
X component of velocity Vx= V*cos24 =11.876 m/s
distance =4.2 meter
time =distance/speed =4.2/11.876 =0.3537 s
b) Vertical component of speed = Vy=vsin24=
5.29 m/s
s=ut+0.5at^2 =5.29880.3537-0.5*9.8*0.3537^2

A ship travels north at 15 km/h for 2 h. What is the ship's displacement in km?
Answers
The ship travels with a velocity of 15 km/h within 2 hours. The distance travelled is the velocity times the time taken that is 30 km to the north.
What is velocity ?Velocity is a physical quantity measuring the distance travelled by an object per unit time. Velocity is the rate of speed and it is a vector quantity having both magnitude and direction. The unit of velocity can be m/s, km/h, ft/s etc.
Velocity is the ratio of the change in distance to the change in time. The change in distance is sometimes called the displacement.
then velocity = displacement / time
Given that velocity = 15 km/h
time taken = 2 hours
then displacement = velocity × time
= 15 × 2 = 30 Km
Therefore, the displacement of the ship is 30 km to the north.

What is the gravitational force acting on a 53 kg object standing on the surface of the Earth?
a) 5.3 N
b) 63N
c)48N
d) 530N
Answers
Answer:
D.
Explanation:
DId the test
The gravitational force acting on the body of mass 53 Kg on earth will be 530 Newtons.
What is Weight ?
Weight is the force exerted by earth on a body on the surface of earth. Mathematically -
W = mg
Given is a 53 kg object standing on the surface of the Earth.
The gravitational force acting on the body will be same as it weight and will be directed towards the center of earth. Using the formula for weight -
W = mg = 53 x 10 = 530 N [taken g = 10 m/s²]
Therefore, the gravitational force acting on the body of mass 53 Kg on earth will be 530 Newtons.
