Question

A particle travels 400 meters after starting from rest on 20 seconds. Find the acceleration of the moving particle.​

Answer 1

Answer:

Explanation:

acceleration=final velocity-initial velocity/time taken

final velocity=speed=distance/time=400/20=20m/s

A=20-0/20=1m/s^2

final velocity=20 and time =20 initial velocity-rest=0

Answer 2

Answer:

a=20m/s²

Explanation:

d=400m

t=20s

u=initial velocity=0m/s

a=?

Solⁿ:d=u+at

400=0+(a)20

400=20a

Hence a=20m/s²
