A ball is thrown horizontally from the top of a 24.7 m building with a speed of 13.2m/s. Assuming level ground, the ball lands ___ m from the base of the building.

The horizontal distance traveled by the ball is 29.7 m.

Explanation:

Given;

height of the building, h = 24.7 m

initial horizontal velocity, Vₓ = 13.2 m/s

The time taken for the ball to fall from the vertical height is calculated as;

where;

is initial vertical velocity = 0

The horizontal distance traveled by the ball is calculated as;

Therefore, the horizontal distance traveled by the ball is 29.7 m.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
