When you shoot a basketball at a basket, the energy from your hands is transferred into the basketball. When you hold the ball up in preparation to shoot, it has potential energy, meaning that it has stored energy that can turn into kinetic energy. When you shoot it, that potential energy turns into kinetic energy, causing the basketball to move.
Answer:
8.64 x 10^7 J
Explanation:
Intensity of sunlight, I = 1000 W/m^2
Length of panel, L = 6 m
Width of panel, W = 4 m
Area of the panel, A = L x W = 6 x 4 = 24 m^2
time, t = 1 hour = 3600 second
Energy = Intensity x area of panel x time
E = 1000 x 24 x 3600 = 8.64 x 10^7 J
Let's use Newton's 2nd law of motion:
Force = (mass) x (acceleration)
Force = (68 kg) x (1.2 m/s²) = 81.6 newtons .
