The tension in the string is 16⋅0 N when the system is set into motion. Find the decrease in the gravitational potential energy during the first second after the system is released from rest.A 0.73 kg mass is attached to the end of a spring and set into oscillation on a horizontal frictionless surface by releasing it from a compressed position. The record of time is started when the oscillating mass passes through the equilibrium position and the position of the mass at any time is shown in the drawing. Determine the following.For example, the force needed to accelerate a 10 kg mass by 5 m/s 2 is 10 × 5 = 50 N The same force could accelerate a 1 kg mass by 50 m/s 2 or a 100 kg mass by 0.5 m/s 2 .
