Question

10. A body starting from rest travels
with uniform acceleration. If it
travels 100 m in 5 seconds, what
is the acceleration?
(a) 10 m/s2
(6) 8 m/s2
(c) 6 m/s2
(d) 4 m/s2​

Answer 1

Answer :

20 m/s ^2

Step-by-step explanation:

U = 0 m/s

V = 100 m/s

T= 5 sec

A = v - u

t

= 100 - 0 = 100 = 20 m/s ^2

5 5

Answer 2

Step-by-step explanation:

We will use second equation of motion

s=ut+1/2at2

Here u=0m/s

s=100m

t=5s

100=0x5 +1/2a(5)^2

100=1/2x25a

100=25/2a

100x2/25=a

8m/s2=a
