A car starts from rest and attains a velocity of 40 metres per second in 20 seconds. it maintains this velocity for 30 seconds and then comes to rest in 25 seconds. 1. sketch the velocity time graph for the motion.
A cyclist starts from rest and accelerates at 2m/s2, for 2second. Her velocity remains constant for the following 4second. The brakes are then applied and the bicycle decelerates uniformly until it comes to rest after 10 second.
two cars A & B at rest at same point initially if A starts with uniform velocity of 40m/s and B starts in the same direction with constant acceleration of 4m/s^2, then B will catch A after how much time
A body starts from rest and accelerates to a velocity of 5m/s in 20s. It then maintains this velocity for 10s and then decelerates to rest in further 10s. (a) Draw a velocity – time graph of the motion (b) Calculate the initial
A car is stopped at a traffic light. It then travels along a straight road such that its distance from the light is given by x(t) = bt^2 - ct^3, where b = 3 m/s^2 and c = 0.110 m/s^3. a) Calculate the average velocity of the car
A car starts from rest and attains a velocity of 40 metres per second in 20 seconds. it maintains this velocity for 30 seconds and then comes to rest in 25 seconds. Calculate the total distance covered by the body
