Question

if a auto mobile of 1000 kg draw a engine with the speed 10m/s. then how many power will be ? the solution of this problem

Answer 1

Answer: P=Fv=mgv=1000 kg*9.80665 m/(s^2)*10 m/s= 98066.5 kg*m^2/(s^3)=98066.5 (watt), where P - power, F - force, m - mass, v - speed, g - the Earth's standard acceleration due to gravity
