Answer 1

$\huge\mathfrak\red{question:)}$

A truck driver decrease the velocity of truck from 100m/s to 50m/s in 5 second. Find the acceleration of the truck.

$\huge\mathfrak\red{answer:)}$

Given Final velocity (v) = 50 m/s

Initial velocity (u) = 30 m/s

Acceleration (a) = 2.5 m/s

2

We know v = u + at

∴ 50 = 30 + 2.5 t

⇒ 50 - 30 = 2.5 t

⇒

2.5

20

= t or 8 = t

∴ Time taken to accelerate = 8 seconds
