Question

a car is travelling at 36 km per hour its if its velocity increases to 72 km per hour in 5 second then find the acceleration of the car in SI units​

Answer 1

the acceleration is the= 72-36/5=7.2×5/18= 2m/s ans

Answer 2

Explanation:

u=36k/hr=36×(5/18)=10m/sec.

v=72km/hr=72×(5/18)=20 km/hr

time=5sec

acceleration =(v-u)/t=(20-10)/5=10/5=2m/sec^2
