A man stands on top of a slope and starts to cycle DOWNWARDS. His MASS (with the bicycle) is 64 kg.
The efficiency that converted the gravitational potential energy (energy in)-Eg- to kinetic energy (energy out) -Ek- is equal to 48%.
Calculate the speed of the bicycle when it is 12 meters(distance) down the slope.
HELP ME PLEASE!
Remember that: Eg =mass*gravity (9.8 m/s2)*height
Ek=(1/2)*mass*velocity squared
Efficiency = E out/ E in multiplied by 100 (in this case= Eg/Ek multiplied by 100)
