Question

A body increases its velocity from 50 m/s
to 70 m/s, it covers a distance of 500m, the
acceleration of the body is
Ans-4 ms
4 ms
1) 74 m2
ms-2
2) 441
4) 73 m2
3) 34 ms​

Answer 1

u= 50

v= 70

D= 500m

v= Distance / Time

Time = Distance/velocity

= 500/20=25

A = v-u/t m/s2

= 70--50/25 m/s2

=4/5 m/s2

=0.8 m/s2

Answer 2

Answer:

0.8m/s² is the answer
