K.C.S.E Physics Q & A - MODEL 1998PP1QN34
Fig 12 shows a body of weight 50N placed on a surface which is inclined at an angle of 30 to the horizontal . The body experiences a maximum frictional force of 29N with the surface.
Determine the force required to move the body, up the inclined with constant velocity.

Figure 4 shows a force- distance graph for a car being towed on a horizontal groun
(a) Calculate the total work done
(b) If the velocity just before reaching point D is 0.6ms-1, calculate the power developed by the agent providing the force at this point.
(c) An electric pump can raise water from a low level reservoir to the higher – level reservoir at the rate of 3.0 x 105 kg per hour. The vertical height of the water raised 360m. If the rate of energy loss in form of heat is 200KW, determine the efficiency of the pump
