A 50 Newton horizonal force pushes a 10 kg mass sitting on a horizontal surface. Additionaly, the horizonal surface exerts a 25 Newton frictional force on the mass. What is the acceleration of the mass?
A 50kg mass, initially at rest, is pushed up an inclined planeby a 400N force acting parallel to the plane. After moving 3.0m upthe plane, the mass is moving with a speed of 2 m/s. How much workwas done by friction? (The inclined plane is at 32 degrees abovethe horizontal).
A block of mass 10 kg moving in the X-direction with a constant speed of 10 m/s is subjected to a retarding force during its travel from x=20m to 30m. Its final KE will be__.
