The Figure below shows the path of a projectile launched from ground level with a speed of 25 m s−1 at an angle of 42° to the horizontal.
What is the horizontal distance from the starting point of the projectile when it hits the ground?

The braking distance of a car is directly proportional to its initial kinetic energy.
The braking distance of a car is 18 m when its initial speed is 10 m s−1.
What is the braking distance of the car, under the same conditions, when its initial speed is 25 m s−1?

Two identical balls, X and Y, are at the same height and a horizontal distance of 25 cm apart.
X is projected horizontally with a velocity of 0.10 m s–1 towards Y at the same time that Y is released from rest. Both X and Y move freely in the absence of air resistance.
What is the distance between the balls 1.0 s later?
Question 4 of 10
4 of 10
A projectile is launched with a speed of 25 m s−1 at an angle of 35° to the horizontal, as shown in the diagram.
Air resistance is negligible.
What is the time taken for the projectile to return to the ground?
Question 5 of 10
5 of 10
A pellet with velocity 200 m s−1and mass 5.0 g is fired vertically upwards into a stationary block of mass 95.0 g. The pellet remains in the block. The impact causes the block to move vertically upwards.
What is the maximum vertical displacement of the block?

Small water drops leave a tap with zero velocity at intervals of 0.20 s.
They then fall freely 0.80 m to reach a horizontal surface.
How far has a drop fallen when the previous drop hits the surface?

A suitcase weighing 200 N is placed on a weighing scale in a lift.
The scale reads 180 N when the lift is moving.
The lift is

A golf ball was hit from the surface of the Moon. The time of flight was 4.0 s.
What is the best estimate for the maximum height reached by the ball?
Acceleration due to gravity on the Moon = 1.6 m s–2.
