A block of mass 0.1 kg is attached to a spring of spring constant 11 N/m on a frictionless track. The block moves in simple harmonic motion with amplitude 0.13 m. While passing through the equilibrium point from left to right, the block is struck by a bullet, which stops inside the block. The velocity of the bullet immediately before it strikes the block is 47 m/s and the mass of the bullet is 3.49 g. If the simple harmonic motion after the collision is described by x = B sin(? t + ?), what is the new amplitude B? Answer in units of m The collision occurred at the equilibrium position. How long will it take for the block to reach maximum amplitude after the collision? Answer in units of s
A 2.50-g bullet travelling at a speed of 425 m/s, strikes the wooden block of a ballistic pendulum, such as that Figure in 7.12. The block has a mass of 215 g. Calculate the speed of the bullet/block combination quickly after the collision.
The nucleus in an iron atom has a radius of about 4.0 X 10-15 m and contains 26 protons, What is the magnitude of the gravitational force between those same two protons
Two cars are travelling on a desert road. After 5s, they are side by side at the next telephone pole. The distance between the poles is 70m.
A coin slides over a frictionless plane and across an xy coordinate system from the origin to a point with xy coordinates (1.4 m, 5.7 m) while a constant force acts on it. How much work is done by the force on the coin during the displacement
