two blocks of masses m and 3m are placed on a frictionless, horizontal surface. a light spring is attached to the more massive block, and the blocks are pushed together with the spring between them as shown in the figure below. a cord initially holding the blocks together is burned; after that happens, the block of mass 3m moves to the right with a speed of v with arrow3m = 2.70 m/s.(e) if the spring was compressed by 5.00 cm, what is the spring constant of the spring?

Figure shows a ballistic pendulum, a simple system for measuring the speed of a bullet. A bullet of mass mB makes a completely inelastic collision with a block of wood of mass mW, which is suspended like a pendulum. After the impact, the block swings up to a maximum height h. In terms of h, mB, and mW, what is the initial speed v1 of the bullet?
Chapter 09, Problem 058 In the figure, block 2 (mass 1.80 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 185 N/m. The other end of the spring is fixed to a wall. Block 1 (mass 1.00 kg), traveling at speed v, = 4.40 m/s, collides with block 2, and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed? 2 0000 Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work
In the "before" part of the figure, car A (mass 1200 kg) is stopped at a traffic light when it is rear-ended by car B (mass 1300 kg). Both cars then slide with locked wheels until the frictional force from the slick road (with a low μk of 0.20) stops them, at distances då = 7.9 m and dB = 6.2 m. What are the speeds of (a) car A and (b) car B at the start of the sliding, just after the collision? (c) Assuming that linear momentum is conserved during the collision, find the speed of car B just before the collision. Before After (a) Number Units (b) Number Units (c) Number Units B B
A 3.12-kg steel ball strikes a massive wall at 10.0 m/s at an angle of ? = 60.0° with the plane of the wall. It bounces off the wall with the same speed and angle (see the figure below). If the ball is in contact with the wall for 0.210 s, what is the average force exerted by the wall on the ball? magnitude N direction (direction options: +y direction, -y direction, +x direction, -x direction)
Problem: You are lead engineer on the design of a crash test apparatus that verifies collisions of varying types. A m = 2 kg mass, when suspended above from a light-weight wire of L = 1.5 m, is first released at an angle of 90°, and correspondingly a height h = L. The tethered ball swings toward the waiting block of M = 4 kg. collides, then rebounds back to an angle of 0 = 32°. In this case, the collision between m and M is elastic, which prompts M's rightwards motion a distance of Ax = 2.1 m, from which the coefficient of kinetic friction between the block and surface on which it is slid is determined. m L h 0 M
A 6.0 ✕ 104 kg space probe is traveling at a speed of 12000 m/s through deep space. Retrorockets are fired along the line of motion to reduce the probe's speed. The retrorockets generate a force of 3.0 ✕ 105 N over a distance of 2400 km. What is the final speed of the probe? m/s

Ball A, with a mass of 2kg, is thrown at a speed of 4 m/s to a suspended ball of 20kg mass, which is standing still. If the coefficient of return between the ball and the block is e=0.8, what is the maximum height H when the block momentarily stops during the collision?
Block A (with mass 10 kg) slides along a frictionless floor with a speed of 0.75 m/s and collides with Block B (with mass 12 kg) which was at rest and is attached to a spring with spring constant 24 N/m. The blocks stick together after the collision; what is the maximum compression of the spring?

A 0.663-kg ball, initially moving with a speed of 3.09 m/s, bounces off a wall and then moves with a speed magnitude half of its original directed in the opposite direction. If the ball is in contact with the wall for 5.4 ms, what is the magnitude of the average force that the wall exerts on the ball? Express your answer in two decimal places, in Newtons.
You awaken in the night to find that your living room is on fire. Your one chance to save yourself is to throw something that will hit the back of your bedroom door and close it, giving you a few seconds to escape out the window. You happen to have both a sticky ball of clay and a super-bouncy Superball next to your bed, both the same size and same mass. You've only time to throw one. Which will it be? Your life depends on making the right choice! O Throw the Superball Throw the ball of clay It doesn't matter, Throw either
