A factory worker pushes a 28.6 kg crate a distance of 4.9 m along a level floor at constant velocity by pushing downward at an angle of 32 degrees below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.26.A) What magnitude of force must the worker apply to move the crate at constant velocity?B) How much work is done on the crate by this force when the crate is pushed a distance of 4.9 m?C) How much work is done on the crate by friction during this displacement?D) How much work is done by the normal force?E) How much work is done by gravity?F) What is the total work done on the crate?
In a slow-pitch softball game, a 0.200 kg softball crossed the plate at 18.00 m/s at an angle of 45.0° below the horizontal. Determine the impulse delivered to the ball
The mass of the earth can be given as 10 moles of kilograms. What does this statement mean, and what is the error with the actual mass of the earth (5.98 x 1024 kg)

A proton accelerates from rest in a uniform electric field of 625 N/C. At one later moment, its speed is 1.25E+06 m/s. Over what time interval does the proton reach this speed
You drive on Interstate 10 from San Antonio to Houston, half the time at 60 km/h and the other half at 105 km/h. On the way back you travel half the distance at 60 km/h and the other half at 105 km/h.
A massive steel cable drags a 20.0kg block across a horizontal, frictionless surface. A 115N force applied to the cable causes the block to reach a speed of 4.30m/s in 2.30s. What is the difference in tension between the two ends of the cable?
A 4.30-kg ball is dropped from a height of 14.5m above one end of a uniform bar that pivots at its center. The bar has mass 6.50kg and is 4.60m in length. At the other end of the bar sits another 6.00-kg ball, unattached to the bar. The dropped ball ..
