Question

A car increases its speed from 30 km/h to 40km/h l in 5 sec. Find the acceleration of car.​

Answer 1

Answer:

acceleration is given by the change in velocity wrt to time.

so the total change in velocity is 10km/s.

acceleration is given by taking care of unit of the time and distance both

=10× 1000÷5×3600

= 10× 10÷ 5× 36

= 100÷ 180

= 20÷ 36

= 10÷ 16

= 5÷ 8

so answer is 5/ 8 m/s.
