A car is parked on a 20 degree hill It has a mass of 1550 kg What is the frictional force on the car class=

Respuesta :

Answer:

Explanation:

The friction force must balance (acting up slope) the weight component of the car (acting down slope)

Ff = mgsinθ

Ff = 1550(9.8)sin20

Ff = 5,195.28597...

Ff = 5200 N
