Question

...........

A spring with a force constant of 105 N/m is used to push a 0.27 kg block of wood against a wall, as shown in Figure 6-19. Figure 6-19 Find the minimum compression of the spring needed to keep the block from falling, given that the coefficient of static friction between the block and the wall is 0.37. cm(b) How does your answer to part (a) change if the mass of the block of wood is quadrupled? spring displacement increases by a factor of 16 spring displacement decreases by a factor of 4 spring displacement decreases by a factor of 16 spring displacement increases by a factor of 4

Explanation / Answer

mg=mew*kx

0.27*9.8=0.37*105*x

x=0.068m

x=6.8cm

b)if the mass of block is quadrupled

spring displacement will increase by a factor of 4
