Question 4 d)

True

or false: If Shepard had hit the golf ball with a velocity of 25 m/s with an

angle of 45° to the horizontal, the golf ball would have

travelled further.

Question 4 b)

How

far horizontally did the golf ball travel? Give your answer to 1 decimal place

in units of m. Write your answer without units i.e., 12.6 m as 12.6.

Question 4 a)

On February 6, 1971, Apollo 14 astronaut Alan Shepard

connected his custom-made golf club head attachment to a tool designed

primarily to scoop lunar rock samples. He then hit two golf balls on the

surface of the Moon. The first ball was a bit of a dud, but the second attempt

resulted in a clean stroke, with the ball hit at a speed of 23.5 m/s at an

angle of 40° with

the horizontal. Assume that the free-fall acceleration,

Question 3 b)

What is the total time the coin is in the air

(from release to hitting the water at the bottom of the well)?

Give your answer to 1 decimal place in

seconds. Write your answer without units i.e., 12.6 s as 12.6.

Question 3 a)

From level with the ground, a coin is tossed straight up

with a speed of 15.0 m/s. When it returns, it falls into a well containing

water 15.0 m below the surface.

What is the coin’s velocity as it hits the water

at the bottom of the well?

Question 2 f)

What

is the ball’s (average)

Question 2 e)

The

ball’s velocity

Question 2 c)

The

change in the ball’s position from

Question 2 d)

What

is the ball’s velocity before reaching the sticky section of track? Give your

answer in whole numbers in units of m/s. Write your answer without units i.e.,

12 m/s as 12.

Question 2 a)

A

ball rolls horizontally along a track. A camera takes a picture of the ball 4

times every second and the position of the ball at each photograph is shown in

the diagram below (note the leftmost ball position is the first photograph,

with each subsequent photograph showing the movement of the ball towards the

right of the track).

Which

of the graphs of position,
