A 45.8-kg girl is standing on a 161-kg plank. Both originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity of 1.44i hat bold m/s relative to the plank.
(a) What is the velocity of the plank relative to the ice surface?
(b) What is the girl's velocity relative to the ice surface?
An electron is released from rest at x=0 in a region where the electric field is . Find the speed of the electron when x = 2.5 cm
One of the fragments falls straight downward as though it had been released from rest. Explain how far from the gun does the other fragment land
What is the magnitude of the acceleration of a modified Atwood machine if the mass of the cart is 3 kg and the hanging mass is 4 kg? (Use g = 9.8 m/s2. Express your answer to one decimal point.)
Determine the magnitude of the friction force. 5.80 g lead bullet traveling at 460 m/s is stopped by a large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet while the other half is tra..
A 48.0 ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 2.50 turns each second. The distance from one hand to the other is 1.50. Biometric measurements indicate that each hand typically makes ..
