12th grade Physics

posted by on .

A boy pushes a lawn mower with a mas of 17.9 kg starting from rest across a horizontal lawn by applying a force of 32.9N straight along the handle, which is inclined at an agle of 35.1 degrees above the horizontal. The magnitude of the mower's accelerations is 1.37m/s^2, which lasts for 0.58 s after which the mower moves at a constant velocity. Determine the magnitude of:
A)the normal force on the mower
B)the frictional force on the mower
C)the maximum velocity
d) the force applied by the boy needed to maintain the constant velocity.

    Please do not just "drop off" problems. Show your work. Do you know what "the normal force" means? It is the component of the applied force that is perpendicular to the ground. Start by calculating that.
