Question

A particle is projected vertically upwards with initial velocity 25 m per second during third second of its motion which of the following statement is true

displacement=30m
distance=30
distance covered )2.5​

Answer 1

vertically upwards

so,

y - direction

uy = 25 m/s

ay = -g = -10

t = 3 sec

s = ut + 1/2 at ²

= 25*3 + 1/2 * -10 * 9

= 75 - 45

= 30 m

so, displacement = 30 m
