A particle accelerated uniformly from rest with 2 ms-2 for 5 seconds and then it retards uniformly and comes t rest after the next 3 seconds. If the total distance covered is 70m, calculate the retardation produced.

Answer:
A body starting from rests accelerates uniformly along a straight line at the rate of 10 ms
−2
for 5 seconds. It moves for 2 second with uniform velocity of 50 ms
−1
. Then it retards uniformly and comes to rest in 3s. Draw a velocity-time graph of the body and find the total distance traveled by the body.
Hard
Answer
Total distance travelled = Area under the v – t graph
=1/2×50×(10+2)
=300m
