Q1.

The figure below shows a toy car in different positions on a racing track.

The car is released from rest at position A and accelerates due to gravity down the track to position B. 

mass of toy car = 0.040 kg 

vertical height between position A and position B = 90 cm 

gravitational field strength = 9.8 N/kg 

Calculate the maximum possible speed of the toy car when it reaches position B.
