Question

A body moves with a velocity of 2m/s for 5s then it's velocity increases uniformly to 10m/s in next 5s . Thereafter it's velocity begins to decrease at a uniform rate until it comes to rest after 5s. with a graph , find the total distance covered by the body after 5s and 10s

Answer 1

Hey mate

Here is ur ans

=============

V1 = 2m/sec ; t1 = 5 sec 
S1 = V1*t1 = 2*5 = 10 m 

V2 = 10 m/sec ; t2 = 5 sec 
S2 = (V1+V2)/2*t2 = 6*5 = 30 sec 

t3 = 10 sec 
S3 = 1/2V2*t3 = 5*10 = 50 m 

total space S = S1+S2+S3 = 10+30+50 = 90 m

==================

Hope it helps u ☺☺☺⛤⛤⤴⤴
