Give your answer to the nearest whole number in

units of N. Write your answer without units i.e., 12 N as 12.

This

time, a curler picks up a ‘joke’ stone weighing 40 kg. They launch it at the

same speed as before (3.5 m/s) and again, there is no extra sweeping. Which one

of the following is true?

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.

A

20 kg stone is launched with a speed of 3.5 m/s and travels 42 m before stopping

(without any team members sweeping). What is the magnitude of the friction

force on the stone? Assume constant acceleration. Give your answer to one

decimal place in Newtons. Write your answer without units i.e., 1.2 N as 1.2.

(direction it is

going) of the stone by:

Curling

is a winter sport played on ice where two teams of four players each take turns

sliding heavy granite stones towards a target area called the

"house." Team members are able to sweep the ice in front of the stone

to adjust its speed and trajectory although they are forbidden from touching

the stone. Expert and careful sweeping can lengthen the travel of the stone by

around 3 m.

A

curler pushes a 20 kg stone from rest to a speed of 3.5 m/s over a time of 2.0

s. Ignoring the force of friction (for now) and assuming a constant

acceleration, how much force must the curler apply to the stone to bring it up

to speed? Give your answer in whole numbers in Newtons. Write your answer

without units i.e., 12 N as 12.

At

first, the driver pulls on the rope, but the car does not move. What is the

approximate direction of the force of the mud on the car?
