An object of mass ' m ' is projected with an initial velocity ' u ' with an angle of ' ' with the horizontal. The average power delivered by gravity in reaching the highest point.

Options

  1. Amgu ^2 2
  2. Bm u^2 ^2 2 g
  3. Cm g 2 u
  4. Dmgu 2

Correct answer

D. mgu 2

Step-by-step solution

At highest point of the projectile, aligned & P _ av = W _ g ~T 2 = 2 mg H _ T = 2 mg ( u ^2 ^2 2 ~g ) ( 2 u ~g ) & = 1 2 mgu aligned
