Question

how long will it take for a body accelerating by 2m/s to gain a velocity of 10m/s, starting from rest?

Answer 1

Answer:

5 sec

Explanation:

a=2m/s

v=10m/s

u=0

a=v-u/t

2=10-0/t

2t=10

t=10/2

t=5sec

Answer 2

Answer:

Apply first equation of motion,

v=u+at

10=0+2*t

10=2t

t=5 seconds.(Ans).
