A pendulum of length L = 1.0 meter and bob of mass m = 1.0 kg is released from rest at an angle = 30. When the pendulum reaches the vertical position, the bob strikes a cube with mass M = 3.0 kg that is resting on a frictionless table of height h = 0.85 m.
a. When the pendulum reaches the vertical position, calculate the speed of the bob just before it strikes the cube. hint: how high was the bob above the impact point when it started?
b. Calculate the speed of the bob and the cube just after they collide elastically.
c. Determine the impulse acting on the cube during collision
A pendulum of mass m and length is initially at rest at an angle 8. The pendulum
then swings down and collides elastically with a stationary block of mass M. The
block slides along the surface and eventually stops when it encounters a rough
patch of length |Ad|.
Assume that m = 1.7kg, L = 0.80m, 0 = 67, M 2.8kg and Ad = 0.55m.
a) Calculate the speed of the block immediately after the elastic collision.
b) What is the coefficient of kinetic friction of the rough patch?
A net force along the x-axis that has x-component Fx=−12.0N+(0.300N/m^2)x^2 is applied to a 4.60 kg object that is initially at the origin and moving in the −x direction with a speed of 8.60 m/s.
