Answer:
a) speed of the car = 22.22 m /s
b) ( i )
Explanation:
Negative work done by friction will be equal to reduction in kinetic energy of the car.
Frictional force = μ R = μ mg
work done by it = μ mg x 70 m.
Change in kinetic energy = 1/2 m v²
So , μ mg x 70 = 1/2 m v² ------------- ( 1 )
v = √2 x μ x 70 x g
= √2 x .36 x 70 x 9.8
22.22 m/s
As we have seen that m cancels out on both side of equation no ( 1 )
