Calculate the impulse of the force acting on the ball in kg m/s.

Calculate the mass of the ball in kg in two significant figures

Calculate the height (in meters) to which the ball rises. Ignore air resistance.

The figure shows a collision between two blocks A and B on a smooth, horizontal surface. Calculate the momentum of block A before collision in two significant figures.

Calculate the velocity (v) after collision in two significant figures.

Calculate the impulse experienced by block B during the collision (two significant figures)

The mass of a car is 1400 kg. The car is initially at rest, is moved along a level road by a resultant force of 3500 N. The car reaches a speed of 30 m/s.

Calculate the acceleration of the car in m/s²

The mass of a car is 1400 kg. The car is initially at rest, is moved along a level road by a resultant force of 3500 N. The car reaches a speed of 30 m/s.

Calculate the time for which the force is applied.

A truck accelerates uniformly along a straight, horizontal road. The mass of the truck is 2.0 x 10⁴ kg. The speed of the truck increases from rest to 12 m/s in 30 s.

Calculate the distance (m) travelled by the truck during this time.

A truck accelerates uniformly along a straight, horizontal road. The mass of the truck is 2.0 x 10⁴ kg. The speed of the truck increases from rest to 12 m/s in 30 s.

Calculate the resultant force on the truck in Newtons (N).
