Question

What will be the acceleration of an object after 10 sec which is moving with constant velocity of 40 m/s?

Answer 1

When an object is moving with constant velocity then change in acceleration would be zero,

i.e., u = v = 40 m/s

\(a=\frac {\upsilon -u}{t} =\frac {40-40}{10} =\frac {0}{10} =0m/{s}^{2} \)
