A 1620-kg car coasts 25m down a hill at an angle of 60 . If the total work done is 3.75 x 104 J, a) find the magnitude of the force of friction, and b) what is the coefficient of friction?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

volts times amps 6 x 0.5 3w

your answer is, orbit around the nucleus

answer: 31, 5556. 952 seconds
