Question

A vertical spring (ignore its mass), whose spring constant is 875 N/m , is attached to a table and is compressed down by 0.160 m. What upward speed can it give to a 0.320-kg ball when released?

A vertical spring (ignore its mass), whose spring constant is 875 N/m , is attached to a table and is compressed down by 0.160 m.

A) What upward speed can it give to a 0.320-kg ball when released?

I tried 7.88 m/s, but it said "Review your calculations; you may have made a rounding error or used the wrong number of significant figures." What would the correct answer be? It wants it in 3 sig figs.

B) How high above its original position (spring compressed) will the ball fly?

Answer 1

Answer #1

Finally figured out how to do it. No thanks to everyone else who gave the wrong answers in the other posts. Then proceeded to recommend the wrong answers. Not helpful at all.

The correct answers are:

A) 8.18 m/s

B) 3.57 m

A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 75 N/m and negligible mass.

A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 75 N/m and negligible mass. At time t = 0 the mass is released from rest at a distance d = 0.35 m below its equilibrium height and undergoes simple harmonic motion with its position given as a function of time by y(t) = A cos(wt - φ). The positive y-axis...

ONLY attempt to solve if you know what you are doing. A mass of 1 kg is attached to a spring whose constant is 5 N/m. Initially, the mass is released 1 m below the equilibrium position with a downward velocity of 5 m/s, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 2 times the instantaneous velocit y. a) Find the equation of motion if the mass is driven...
