Question

a boby covers a initial velocity of 5m/s and uniform acceleration of 2.5m/s what is the displacement after next 4 sec​

Answer 1

Answer:

40 m

Explanation:

According to the given question,

u = initial velocity = 5 m/s

a = acceleration = 2.5 m/s^2

t = time = 4 sec

s = displacement = ?

And we are asked to find displacement.

In this question displacement is equal to distance as it's a linear motion (Not written in question so we can assume).

We know,

• s = ut+1/2 at^2

Putting the values we get,

• s = 5×4 + 1/2× 2.5×(4)^2

• s = 20 + 20

• s = 40 m

Thus body will cover 40 m after 4 sec if it's initial velocity is 5 m/s And acceleration is 2.5 m/s^2.
