Question 4 c)

Ignoring

air resistance, how much

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 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 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 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 e)

The

ball’s velocity

Question 2 f)

What

is the ball’s (average)

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.
