Question

a particle travels 100 m after starting from rest in 10 s its acceleration is

Answer 1

Hey dear here is your answer.....

Let u =0m/sec
Let the=10 sec

S=ut+1/2at^2
100=0+1/2a100
200=100a
a=2m/sec^2

hope it may helps u ...

Answer 2

Let, s=distance covered by the particle.
u=primary velocity of particle.
f=acceleration of particle.
t=time
Then, we have
s=ut + (1÷2)×f×(t^2)
here s=100m t=10 sec u=0
so, 100= 0+ (1÷2)×f×100
or, f=2 m/(sec^2)
