Question

A particle covers 50m. distance when projected with an
initial speed. On the same surface it will cover a distance,
when projected with double the initial speed -
(1) 100 m (2) 150 m (3) 200 m (4) 250 m​

Answer 1

Answer 2

Answer:

200 m

Since the type of projection is not mentioned , let us consider it as vertically projected body

H = u² / 2g

50 = u² / 2g

H2 = 4u² / 2g

h1 : H2 = u² / 2g : 4u² / 2g

1:4

50 : x = 1 : 4

x = 200

Hence H2 = 200 m

And therefore , the distance will be 200 m
