A 2.90-kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring.

(a) Determine the force constant of the spring, if the box compresses the spring 5.30 cm before coming to rest.

(b) Determine the initial speed the box would need in order to compress the spring by 1.50 cm.

Expert Solution

As Surface is frictionless hence no friction force will be present. So only spring force will act on the box.

Then work energy theorem is applied to find the force constant of the spring.

Solution is given below with proper steps

A 0.990 kg block slides on a frictionless, horizontal surface with a speed of 1.40 m/s. The block encounters an unstretched spring with a force constant of 231 N/m. Before the block comes to rest, the spring is compressed by 9.17 cm. 1) Suppose the force constant of the spring is doubled, but the mass and speed of the block remain the same. By what multiplicative factor do you expect the maximum compression of the spring to change? Explain. 2)...

A block of mass m = 1.0 kg sliding along a rough horizontal surface is traveling at a speed v0 = 10.0m/s when it strikes a massless spring head-on (see figure) and compresses the spring a maximum distance X =0.25m. If the spring has stiffness constant k = 100. N/m, determine the coefficient of kinetic friction between block and surface.
