Question

A particle is moving along a straight line in same direction with constant acceleration. At the end of
tenth second its velocity becomes 20 m/s and in tenth second it has a displacement of 10 m. Then the
acceleration of the particle will be-​

Answer 1

Hii its tom85

given

v = 20m/s

t = 10s

s= 10m

u = v - at

u = 20 - 10a

s = ut + at^2/2

10 = 200 -100a + 50a

-50a = -190

a = 19/5 = 2 .8 m/s^2
