Question

a trolley while going down an inclined plane has an acceleration of 4m/s. What will be its velocity after 2 seconds?
​

Answer 1

Answer:

u is initial velocity, v is final velocity, a is acceleration and t is time

Explanation:

u=0 m/s

a= 4 m/s^2

t= 2 s

v= u+at

v= 0+(4*2)

v= 0+8

v= 8 m/s
