A MASS DESCENDING AN INCLINED PLANE A mass of 4.0 kg slides along a surface towards an inclined plane with an initial speed of 6.0 m's. The initial height of the mass is 8.0 m above the ground. The angle of inclination of the plane with the ground is 240. (a) If there is no friction, what is the speed of the mass when it reaches the bottom of the incline? (b) If the coefficient of kinetic friction is 0.075, what is the speed of the mass when it reaches the bottom of the incline? Vi = 6.0 mls C m V's ? 8.0 m 24 in V
