Question

Review. A light spring of force constant 3.85 N/m is compressed by 8.00 cm and held between a 0.250-kg block on the left and a 0.500-kg block on the right. Both blocks are at rest on a horizontal surface. The blocks are released simultaneously so that the spring tends to push them apart. Find the maximum velocity each block attains if the coefficient of kinetic friction between each block and the surface is(b) 0.100

Answer 1

The answer is 0.245N.

What is kinetic energy?

• A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
• Kinetic energy comes in five forms: radiant, thermal, acoustic, electrical, and mechanical.
• The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.
• Explain that a moving object's mass and speed are two factors that impact the amount of kinetic energy it will possess.

(b) 0.100

For the block on the left, $f_{k} =u_{k} n= 0.100(2.45N)=0.245N.$

∑$F_{x}$=$ma_{x}$

–0.308N+0.245N=(0.250kg)a

a=−0.252$m/s^{2}$ if the force of static friction is not too large.

For the block on the right, $f_{k}$ =$u_{k} n$=0.490N. The maximum force of static friction would be larger, so no motion would begin, and the acceleration is zero
