Martha is pushing a 35 kg chair across the floor. The coefficients of friction between the chair and floor are ? s = 0.70 and ? k = 0.40.
a. How hard does she need to push horizontally to just start the chair moving?
b. If she applies this same force once it is moving, then what is the resulting acceleration? Draw the free-body diagram for this situation.
A teenager of mass m1 = 68 kg pushes backward against the ground with his foot as he rides his skateboard. This exerts a horizontal force of magnitude Ffoot = 15 N. The skateboard has m2 = 2.6 kg.
a) 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.
b) What is the numerical value for the magnitude of the acceleration, a, in m/s2?
Two blocks, m1 = 4.0 kg and m2 = 6.0 kg are attached together with a piece of string and pulled along a horizontal frictionless surface as shown. If they accelerate at 3.5 m/s2, find the tension in the string between the blocks. (Hint: Draw a free body diagram for block 2).
