Physics Assessment Part 2

Define acceleration.

The mass of the ball is 0.0075 kg. Calculate the resultant force acting on the ball when it is accelerating downwards at 2.8 m / s².

Describe what happens to the acceleration between t = 0 and t = 0.040 s. Explain why this happens.

By drawing a tangent on Fig. 1.2, determine a value for the acceleration of the ball at t = 0.010 s.

Calculate the speed at which trolley P moves to the left.

Calculate the kinetic energy of trolley Q when it moves at 0.36 m / s.

State the energy transfer that takes place as the spring expands.

State one way in which the motion of the particles in ice differs from the motion of the particles in water.

State the name of the thermal process that transfers energy from the water to the ice.

Calculate the energy transferred from this water as its temperature decreases from 28 °C to 10 °C.
