Question

A body of mass 55 kg, projected at an angle of 45° from the ground with an initial velocity of 15 m/s, acceleration due to gravity is g = 10 m/s^2, what is the maximum horizontal range covered?

(a) 22.5 m

(b) 25 m

(c) 16 m

(d) 15 m

The question was posed to me by my college professor while I was bunking the class.

I'd like to ask this question from Simple Projectile Motion topic in division Motion in a Plane of Physics – Class 11

Answer 1

Correct answer is (a) 22.5 m

Explanation: The formula for horizontal range is R = v^2 (sin 2θ)/g. Here, v = 15, θ = 45°, g = 10. Hence, on solving we will get range as 22.5 m.
