Question

A particle Travels 400 metres after starting from rest in 20 seconds its acceleration is​

Answer 1

Answer:

2m/s^2

Explanation:

s= 1/2f.t^2

400= f/2.400

1=f/2

2=f

Answer 2

Answer:

Given ,

u = 0

S = 400 m

t = 20 sec

S = ut + 1/2 at²

S = 1/2 at²

400 = 1/2 × a × 400

200a = 400

a = 2 m/s²
