ACTIVITY 2
1.
Fill correct answer
in each of the following;
(a) The slope in the velocity-time graph represent __________
(b) The total distance travelled by a body is
represented by ______
(c) The horizontal line in the velocity-time shows
that the body travelling with __________ acceleration
(d) The slope in the displacement-time graph represent
__________
2.
A car accelerates
uniformly from a speed of 80 m/s to a speed of 120 m/s in 1 minute. It then moves
with this speed for 20 seconds and finally decelerates uniformly to a stop
after another 2 minutes. Draw the velocity-time graph to represent the motion
of the car then calculate;
(a) The acceleration of the car
(b) The deceleration of the car
(c) The distance travelled by the car when moving
with the same velocity
(d) The total distance travelled by the car
