Question

A particle starting from rest attains a velocity of
50 ms-' in 5 s. The acceleration of the particle is
(1) 5 m/s2
(2) 10 m/s2
(3) 50 m/s2
(4). 100 m/s2​

Answer 1

Answer:

10m/s2

Explanation:

v= u + at

as particle starts from rest

u =0

v=at

a=v/t

a=50/5

a=10 m/s2

Answer 2

Answer:2) 10m/s2

Explanation:

according to the law

v=u+at

v = 50 m/s

t= 5 sec and u=0 as it starts from rest then

50=0+a×5

50=a×5

50/5=a

a =10 m /s2
