A mass m = 10 kg rests on a frictionless table and accelerated from rest by a spring with spring constant k = 4490 N/m. The floor is frictionless except for a rough patch. For this rough patch, the coefficient of the kinetic friction is µk = 0.5. The mass leaves the spring with speed v = 2.8 m/s. Use work and energy to answer the following questions: (a) How much work is done by the spring as it accelerates...
A ball of soft clay with mass 1 kg falls from a height of 10 m starting at rest. When the clay hits the ground it flattens and comes to a stop. Which of the following is true? Gravity does work on the ball equal to 980 J, and all this energy is dissipated during the deformation of the ball on impact. Gravity does work on the ball equal to 98 J, and all of this energy is dissipated during...
A golf ball (50 g) hit by a club is accelerated from rest to 50 m/s in 2.50 ms. What are the magnitudes of the impulse delivered to the ball and the average force acting on the ball? Impulse = Average Force = A disk of radius 10.0 cm spins about an axis through its center at a constant 5.0 rad/s. What is the linear velocity, centripetal and tangential accelerations of a point on its rim? linear velocity = centripetal...
