Question

A cart acceleration from rest and acquies a speed of 36km /hr in 10 sex.find acceleration

Answer 1

velocity = 36 x 5 /1 8 
velocity = 20 m/s 

acceleration will be = 20 / 10 
acc= 2 m/s²

Answer 2

First convert 36km/hr into m/s because time is given in second
To convert multiply 36km/hr by 5/18
36×5/18=10m/s
therefore velocity is 10 m/s
acceleration=velocity/time
=10/10
=1m/s^2
