A 3.5 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 (in N/m) of the spring, if the box compresses the spring 6.3 cm before coming to rest. (B) Determine the initial speed (in m/s) the box would need in order to compress the spring by 1.7 cm.

As shown in the figure below, a box of mass m = 6.80 kg is sliding across a horizontal frictionless surface with an initial speed v1= 2.90 m/s when it encounters a spring of constant k = 2700 N/m
As shown in the figure below, a box of mass m = 6.80 kg is sliding across a horizontal frictionless surface with an initial speed v1= 2.90 m/s when it encounters a spring of constant k = 2700 N/m. The box comes momentarily to rest after compressing the spring some amount xc. Determine the final compression xc of the spring.

Problem 1 A block of mass m is sliding on a frictionless, horizontal surface, with a velocity vi . It hits an ideal spring, of spring constant k, which is attached to the wall. The spring compresses until the block momentarily stops, and then starts expanding again, so the block ultimately bounces off (see Example 5.6.2). (a) Write down an equation of motion (a function x(t)) for the block, which is valid for as long as it is in contact...

A 0.505-kg block slides on a frictionless horizontal surface with a speed of 1.18 m>s. The block encounters an unstretched spring and compresses it 23.2 cm before coming to rest. (b) For what length of time is the block in contact with the spring before it comes to rest? (c) If the force constant of the spring is increased, does the time required to stop the block increase, decrease, or stay the same? Explain.

A 3kg mass sliding on a frictionless horizontal surface with a speed of 3m/s eventually collided with a spring that is attached to a rigid wall. The spring has a spring constant of 3N/m. The masses will compress the spring, and eventually get pushed back away from the wall. A) what will the final speed of the be after it gets pushed back outward? Explain B) By what length is the spring maximally compressed? C) What will the magnitude of...

Two boxes are sliding to the right on a horizontal frictionless surface. Box 1 is trailing box 2. Box 1 has a mass of 2 kg and a speed of 5 m/s, while box 2 has a mass of 4 kg and a speed of 3 m/s. Eventually, box 1 catches up to box 2 and experiences a completely inelastic collision with box 2. What is the speed of the two blocks after the collision?

A box with a mass of 5.0 kg is sliding from rest down an incline plane from the top of the plane. The incline is frictionless plane makes an angle of 20◦ with the horizontal and has a height of 2.0 m. At the bottom of the incline plane, the surface levels out to a horizontal surface with a kinetic coefficient of friction of 0.2. A spring with a spring constant of k = 10 N/m is located 5.0 m...
