A body starting from rest accelerate uniformly along a straight line at the rate of 10m/s^2 for 5second.It moves for 2second with uniform velocity of 50m/s. Then it retards
uniformly and come to rest in 3second. Find the total distance travelled by the body. Draw the velocity -time graph

Answer:

A body starts from rest accelerates uniformly along a straight line at the rate of 10 ms-2 for 5 seconds. It moves for 2 seconds with a uniform velocity of 50 ms-1. Then it retards uniformly and comes to rest in 3s. Draw the velocity-time graph of the body and find the total distance travelled by the body.

Explanation:

Total distance travelled =

Area under the v – t graph

= 1/2 × 50 × (10 + 2)

= 300 m

christeenachonedan: thanks

Aswitaa: welcome dear frnd

christeenachonedan: I've a small doubt.

christeenachonedan: the area of this gives the displacement

christeenachonedan: because when velocity is multiplyed with time we get displacement

christeenachonedan: I don't know exactly
