1000 + 0.75*50,000 = ... Your answer is wrong! Use a calculator or a spreadsheet if you can't do it by hand!!!
total mass = m1+m2 = 3 down force on m1 = 9.8 (m1.g) fric force on m2 = 2*9.8/4 = 9.8/2 (m2.g.mk, cuz mk = 0.25 = 1/4) net force = 9.8 - 9.8/2 = 9.8/2 a = net force/total mass = 9.8/2/3 = 1.6 :)
car: velocity = 20/2 m/s = 10 m/s momentum = mass * velocity = 3000*10 kg x m/s player: mass = momentum/velocity = 1120/10 = 112 kg.
weight = mass * gravitational field strength. weight depends on location, mass does not. mass on mars IS THE SAME AS mass on Earth
