Question

A body is moving with a velocity of 10m/s if it starts acceleration with the rate of 2.5m/s2 find out its velocity after 10sec

Answer 1

v=u+at by using this equation we answer this question
u=10m/s ,a=2.5,t=10s.
v=10+2.5x10 
  =35m/s

Answer 2

Answer:

Using the first equation of motion: v = u + at

where: v = final velocity

u = initial velocity = 10 m/s

a = acceleration = 2.5 m/s2

t = time = 10s

v = 10 m/s + 2.5 m/s2 x 10s = 10+25 m/s = 35 m/s
