Question

A body with an initial velocity of 8 m/s accelerates uniformly at the rate of 9cm/s2. If the distance covered by the body is 200 m, calculate 2M
a) The final velocity
b) the time taken to cover the distance (in SI Units)

Answer 1

Answer:

Given, initial velocity u=18kmh  

−1

 

                                      =  

60×60

18000m

​

=5ms  

−1

 

Acceleration a=0.09ms  

−2

 

and distance s = 200 m

From equation of motion v

We get, v=
