I've tired everything i can think of, anyone that can be of any help i would appriceate it.
A block with a mass of 5 kg is held in equilibrium on an incline of angle = 30.0° by the horizontal force, F, as shown in Figure 4-31. Find the magnitude of F.
( ) N
Find the normal force exerted by the incline on the block. (Disregard friction.)
( )N
and
A box of books weighing 209 N is shoved across the floor by a force of 500 N exerted downward at an angle of 35° below the horizontal.
(a) If µk between the box and the floor is 0.57, how long does it take to move the box 10 m, starting from rest? (If the box will not move, enter 0.)
[ ] s
(b) If µk between the box and the floor is 0.75, how long does it take to move the box 10 m, starting from rest?
