Physics

A block of mass M = 10.0 kg is given an initial speed v0 = 2.10m/s from height hi down a frictionless incline plane of angle θ =75◦. After it reaches the bottom of the incline, it continues toslide on a horizontal surface of coefficient of kinetic friction µk =0.15. After sliding a distance d = 1.8 m along the horizontalsurface, the block moves at a speed v = 7.00 m/s. Magnitude ofacceleration due to gravity is g = 10 m/s2. 14 pt At what initialheight hi on the plane was it released from? 5.A 2.50 m B 1.96 m C2.23 m D 0.65 m E 2.41 m.
