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.
A 2.80-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 5.50 cm before coming to rest. b. Determine the initial speed the box would need in order to compress the spring by 1.30 cm. A box slides from rest down a frictionless ramp inclined at 39.0° with respect to the horizontal and is stopped at the bottom of...
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.
A 740 g box is pressed against a spring on a frictionless surface. The spring is compressed 7.69 cm and the box slides away at a speed of 2.15 m/s. What is the spring constant for 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.
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 block of mass 2.0 kg sliding on a horizontal frictionless surface is attached to one end of a horizontal spring (k = 800 N/m) which has its other end fixed. If the speed of the block as it passes through the equilibrium position is 4.0 m/s, what is its speed when it is a distance of 10 cm from the equilibrium position? a) 3.2 m/s b) 3.5 m/s c) 2.9 m/s d) 2.4 m/s
Figure 15-34 shows block 1 of mass 0.200 kg sliding to the right over a frictionless elevated surface at a speed of 8.00 m/s. The block undergoes an elastie collision with stationary block 2, which is attached to a spring of spring constant 1208.5 N/m. (Assume that the spring does not affect the collision.) After the collision, block 2 oscillates in SHM with a period of 0.140 s, and block 1 slides off the opposite end of the elevated sturface,...
