Question

For the same angle of projection, if we double the speed of projection, then how is the range increases
by a factor of?

Answer 1

Answer:

by a factor angle of inclination

Answer 2

Answer:

Initial Range = R = u^2 Sin2Ø/g

When Ø remains same but u is doubled,

then final U = 2u

So,

Final Range = R2 = (2u)^2 Sin 2Ø/g = 4u^2 Sin2Ø/g = 4R

Hence, range increases by a factor of 4.
