Question

a mass, m = 2.1 kg, is ejected horizontally from a compressed coil with a force constant, k = 5.2 N/m and compression, x = 25 cm, onto a rough ramp that is 1.5 cm long with one end raised to a height, h= 120 cm. the speed at the bottom of the rough ramp is v=+3.037 m/s. the average kinetic friction force of the ramp on the mass is what (in N)?
