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.,

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,

Question 1 b)

What is the speed of the first stone when it hit

the water?

Question 1 c)

What

was the initial speed of the second stone?

Give your answer to 1 decimal place

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