Question

A person started his motion from rest witha constant acceleration of 0.4m/s ... after some time his velocity becomes18m/s. find out the displacement of the person if he travelled in a straight line ?


plzzzzz tell fast .....​

Answer 1

Answer:

s = 405m

Explanation:

acceleration : 0.4m/s^2

final velocity : 18 m/s

initial velocity : 0 m/s

according to third law of motion

v^2 - u^2 = 2as

(18)^2 - (0)^2 = 2×0.4×s

324 - 0 = 0.8s

324 = 0.8s

324/0.8 = s

405 = s

so, displacement of the person is 405m.
