Question

A ball is thrown vertically upwards with velocity 600 metre per second calculate the distance travelled in last 2 second of its upward motion :-

a) 20 m
b) 30 m
c) 10 m
d) 25 m​

Answer 1

Answer:

correct option is (a) 20m........ for the downward u will be zero

Answer 2

Given,

Velocity of the ball=600m/s

To Find,

Distance travelled in last 2 s during its motion.

Solution,

Ball is thrown vertically upwards with 600m/s .

During upward velocityin last 2 seconds distance covered by it,

S=1/2gt²

  =1/2×10×2²

  =1/2×10×4

  =1/2×40

  =20m

Hence, the distance travelled in last 2 seconds is 20m.
