Question

O
A body is moving with an initial velocity of 2 kms". After a time of 50 secs its velocity becomes
1.5 kms". Its acceleration will be:
A) 30 ms
B) 40 ms
C) 20 ms!
D)10 ms

Answer 1

Explanation:

Given, u=0.002 m/s,

t=50 sec,

v=0.0015 m/s,

a=?

we know that, a=v-u/t

a=0.0015-0.002/50

= -0.0005/50

= -0.01 m/s^2

hence, this will be the required ans...

hope this helped
