Question

An object starts its motion from rest. After 40 s it attains a velocity of 25 m/s. From here if it accelerated uniformly at a rate of 5 m/s2, then calculate its velocity at 60th second

Answer 1

Answer:

125 m/s

Explanation:

v = u + at

where v : final velocity

u : initial velocity

a: acceleration

t: time

v = 25 + 5× (60 -40)

= 125 m/s
