Problem 32P
A 1.40-kg block slides with a speed of 0.950 m/s on a frictionless horizontal surface until it encounters a spring with a force constant of 734 N/m. The block comes to rest after compressing the spring 4.15 cm. Find the spring potential energy, u, the kinetic energy of the block, K, and the total mechanical energy of the system, E, for compressions of (a) 0 cm, (b) 1.00 cm, (c) 2.00 cm, (d) 3.00 cm, and (e) 4.00 cm.
ANSWER:
Step 1 of 5
In this problem we need to find the potential, kinetic and total mechanical energies for various cases.
The mass of the block is: .
The speed is: .
The spring constant is: .
After collision, the spring is compressed by, 4.15 cm which is 0.0415 m.
