Hello there!
The Centripetal force keeps an object moving in a circle or constant direction at the same speed.
Hope this helps!
Accelerator pedal and brake pedal
According to the definition of the force, It is defined as <u>the multiplication of the mass and acceleration</u> (or, the rate change of the quantity of motion)
where:
- F: is the force in Newtons (N)
- m: is the mass in kilograms (Kg)
- a: is the acceleration in
Then, in our problem
Power = (energy) / (time)
= (1370 joules) / (100 seconds)
= 13.7 joules/second
= 13.7 watts .
That's not an awful lot of power, especially for a strenuous activity like
rock-climbing. Shoot ! Even I could probably perform at that level.
Compare 13.7 watts to the light power coming out of a 20-watt night light.
13.7 watts = 0.018 horsepower. (rounded)
