Before you step on the brakes, the car has kinetic energy, when you step on the brakes, it turns the kinetic energy into heat (thermal energy). When it stops completely, it has potential energy. Hope this helped :)
Answer:
(θ) = 60°
Explanation:
Given:
Speed of canoe Vc = 2 m/s
Speed of River Vr = 1 m/s
Computation:
Vc (Cosθ) = Vr
2 (Cosθ) = 1
(Cosθ) = 1 / 2
(Cosθ) = (Cos60)
(θ) = 60°
Answer:
P = 3800 W
Explanation:
Power is equal to energy divide by time P = E/t
plug in 4560000 J for energy
convert 20 minutes to seconds
20 * 60 = 1200 seconds
plug in 1200 seconds for time
P = 4560000/1200
P = 3800 W
