31–40 of 67 · Easy
Question 31
3 marks · Easy
Answer and see the solution →A driver is travelling at 30 mph in dry conditions. The thinking distance for this speed is 9 m and the braking distance is 14 m.
(a)[1 mark]Calculate the total stopping distance.
(b)[2 marks]If the driver’s reaction time increases (for example, because they are tired), explain what will happen to the stopping distance.
Question 32
3 marks · Easy
Answer and see the solution →Describe how the following factors each affect a car's braking distance.
Factor Speed of the car Condition of the tyres Mass of the vehicle Give a brief explanation for each factor.

Question 34
2 marks · Easy
Answer and see the solution →Describe what happens to the forces acting on a skydiver just after jumping out of a plane, and how these forces change as the skydiver speeds up.
Question 35
2 marks · Easy
Answer and see the solution →An astronaut drops a tool with a mass of 2.5 kg on a planet where the gravitational field strength is 4 N/kg. Calculate the weight of the tool.
Question 36
3 marks · Easy
Answer and see the solution →Explain why a falling coin eventually stops accelerating and continues to fall at a constant speed. Include what happens to the forces acting on it.
Question 37
2 marks · Easy
Answer and see the solution →Calculate the weight of a backpack with a mass of 3.0 kg on Earth. Use g = 10 N/kg.
Question 38
3 marks · Easy
Answer and see the solution →A tennis ball is dropped from a balcony. It falls straight down through the air.
(a)[1 mark]State the two forces acting on the tennis ball as it falls.
(b)[1 mark]As the ball falls faster, describe what happens to the size of the air resistance.
(c)[1 mark]Eventually the ball falls at a constant speed. What is the name of this constant speed?
Question 39
3 marks · Easy
Answer and see the solution →A cyclist is moving quickly down a hill and eventually reaches a speed where her speed does not increase any further, even though she is still going downhill.
Explain why the cyclist does not keep speeding up. In your answer, refer to the forces acting on the cyclist.
Question 40
1 mark · Easy
Answer and see the solution →A tennis ball has a mass of 0.06 kg. It is moving with a velocity of 10 m/s. Calculate the momentum of the tennis ball.
