Question

a particle moving with a velocity of 5 m/s accelerated uniformly with an acceleration of 2 m/s for 10 s. find the displacement in the last second.

Answer 1

V= 5 m/s a= 2 m/s t = 10 sec

By the 2 nd kinematic eq.
S= ut + 1/2at^2
= 5*10+1/2*2*100
=150


So displacement is 150 m.

Hope this helps
