Q1.
(a) A car accelerates at a constant rate of 1.83 m/s? along a flat straight road.
The force acting on the car is 1.870 KN.
Calculate the mass of the car.
Give your answer to three significant figures.
mass =
(b)
The car accelerates from rest for 16s.
Calculate the speed of the car after 16s.
speed=
(c)
The car starts on another journey. Figure 6 shows the graph of the car’s movement. (Figure at top)
Show that the distance travelled when the car is moving at a constant speed is greater than the distance travelled when the car is slowing down.
