A teenager of mass m1 = 100 kg pushes backward against the ground with his foot as he rides his skateboard. This exerts a horizontal force of magnitude Ffoot = 20 N. The skateboard has m2 = 2 kg.

Part (a) Write an expression for the magnitude of the horizontal component of force that the ground exerts on the teenager's foot, Fground.

Part (b) Write an expression in terms of given quantities for the magnitude of the skateboard's acceleration, a, while the teenager is pushing backwards on the ground.

Part (c) What is the numerical value for the magnitude of the acceleration, a, in m/s²?
