please help me this. NO NEED SOLUTION, physics subject thankss. ASAP

A 200 kg block is pulled at a constant speed of 15.0 mls across a horizontal floor by an applied force of 175 N directed above the horizontal. What is the rate at which the force does work on the block? * O 4.163 kW 0 3.773 kW 0 2.905 kW 0 2.096 kW A 14.00 kg block is pulled up a frictionless inclined plane by a 500.0 N force that is parallel to the plane, starting from rest. The normal force on the block from the plane has magnitude 31.40 N. What is the block's speed when its displacement up the ramp is 13.00 m? * O 4.437 rule 0 13.353 m/s 0 26.082 m/s 0 13.337 rn/s Only two horizontal forces act on a 30 kg body that can move over a frictionless floor. One force is 40 N. acting due east, and the other is 80 N, acting 35 degrees north of west. What is the magnitude of the body's acceleration? * O 2.905 rule\"? 0 2.933 m/s"2 O 4.905 m/s'? 0 3.836 m/s\"2 Our body muscles exert forces when we lift. push, run, jump, and so forth. What do we call these forces? * O Nonoonservative O Tension O Conservative O Compressive
