Question

the velocity of a freely falling body changes as g to the power p× h to the power q ,where g is acceleration due to gravity and h is height the value of p and q are _________​

Answer 1

Hey Dear,

◆ Answer -

p = 1/2

q = 1/2

● Explanation -

Supposed equation is -

v ∝ g^p.h^q

Newton's 3rd law of kinematics,

v^2 = u^2 + 2as

For a freely falling body, u = 0, a = g, s = h,

v^2 = 0^2 + 2gh

v^2 = 2gh

v = √(2gh)

This can be also written as -

v = √2 g^½.h^½

Hence, value of p & q both will be 1/2.
