Question

What is the acceleration if an object which accelerates along a straight path from rest, and attains a velocity of 20 m/s after covering a distance of 50 m is 5 s​

Answer 1

Explanation:

by the 2 equation of motion that is a =ut+1/2at^2

Answer 2

Answer:

Acceleration of the object = 4 m/s²

____________________________

Explanation:

Given data:

• Distance (S) = 50 m
• Initial velocity (u) = 0
• Final velocity (v) = 20 m/s
• Time (t) = 5 s

_______________________

To find:

Acceleration of the object.

_________________________

Solution:

We know that,

v = u + at

(where v is final velocity, u is initial velocity, a is acceleration and t is time.)

⟹ 20 = 0 + a(5)

⟹ 20 = 5a

⟹ a = 20/5 = 4 m/s².
