7. A box of mass 22 kg is at rest on a flat floor. The coefficient of static friction between the box and floor is 0.37. What is the minimum force needed to set the box in motion across the floor?
8. A force of magnitude F stretches a spring a distance of 2 cm from its rest position. What magnitude of force will stretch the spring an additional 4 cm?
9. A force of magnitude 44 N compresses a spring 0.69 m from equilibrium. What is the value of the spring constant?
by hooks lawFa=-kx
F=(-Fa/0.2) * 0.4
twicw then the earliest force will b required
