Question

A car moving with an initial velocity of 60m/s is brought to rest in 30 seconds.Calculate the acceleration​

Answer 1

Answer:

hey!

Explanation:

$a = \frac{v-u}{t}$

u= 60m/s

time=30 secs

friend , as the object is bought to rest,  

v=0m/sec

so,

a= $\frac{0-60}{30}$

=  $\frac{-60}{30}$

= -2
