Question

An object starts moving from the rest with

uniform acceleration and travels 20 m in first

2 s. What will be its velocity after 10 s from

the start and displacement of the particle in

10 seconds?​

Answer 1

Answer:

Newton law of motion

$v = u + at$

V = 20/2 + 20/4*10

V = 10 + 50 = 60 m/s

${v}^{2} - {u}^{2} = 2as$

60^2 - (10)^2 = 2*20/4*s

360 - 100 = 10*s

S = 36-10 = 26 m
