A car acquires a velocity of `72 km//h` in `10` seconds starting from rest. Find (a) the acceleration (b) the average speed ( c ) the distance travelled in this time.

Text Solution

Verified by Experts

Here, initial velocity, u=0
final velocity `v=(72 km)/(h)=(72xx1000 m)/(60 xx60 s)=20 m s^(-1)`
time taken t=10 s
acceleration
`a=(v-u)/(t)=(20-0)/(10)=2 m s^(-2)`
