A crate whose mass is 22.5 kg is being pushed along a floor. There is an opposing horizontal force equal to 70.0 N. The pushing force is 125 N, but it is being applied at an angle of 35.0 degrees above the horizontal. The crate is initially at rest. Determine the following:
a.) the acceleration of the crate
b.) its velocity after 4.00s
c.) its displacement after 4.00s
d.) the normal contact force
