There is a compressed spring between two laboratory carts of masses m1 = 105 g and m2 = 212 g. Initially, the carts are held at rest on a horizontal track (Fig. P10.40A). The carts are released, and the cart of mass m1 has velocity vi=2.035i m/s in the positive x direction (Fig. 10.40B). Assume rolling friction is negligible. a. What is the net external force on the two-cart system? b. Find the velocity of cart 2. FIGURE P10.40 Problems 40 and 41.
A loaded gun is dropped on a frozen lake. The gun fires, with the bullet going horizontally in one direction and the qun sliding on the ice in the other direction. The bullet's mass is 0.04 kg, and its speed is 305 m/s. If the gun's mass is 2.1 kg, what is its speed (in m/s)? m/s
Problem B2. A small box of mass m = 1.50 kg starts from rest and glides down a smooth, frictionless hill from a height h = 2.00 m to the base, where it meets a rough plank of mass M = 5.00 kg that is resting on the frictionless horizontal ground surface. Due to the friction between the box and the plank, its speed is reduced until, at a certain moment, it begins to move together with the plank as if they were a single object. M Figure B2. Problem diagram B2 c) Calculate the work done by the friction forces present in the problem.

A 663 kg hammer of a pile driver is lifted 3.3 meters above a piling head. If the hammer is released, what will be its velocity (in m/s) at the instant it strikes the piling?Correct Answer: 8.0 ± 0.1
Grandma has a new car that uses rocket brakes to slow it down. The car has a mass of 850 kg. She starts out by moving forward with a speed of 12.8 m/s. She then applies the rocket brakes, but as the car comes to a stop she forgets to take her foot off the brake pedal and the rocket continues to apply its force. She ends up moving backwards with a speed of 9.32 m/s. The total time the brakes were firing was 6.74 seconds. (a) Find the change in momentum of the car. (b) Using the formula for impulse, calculate how much force the rocket brake was applying to the car on average, including the direction?
A arrow of mass 0.01 kg moving horizontal suddenly strikes a block of wood of mass 8.6 kg that is suspended by a light string, like a pendulum. The arrow passes through the wood, then the wood swings upward and momentarily stops when the string is horizontal. The length of the string is 2.0 cm. How long did it take the arrow to go through the wood if the friction force between the bullies and the wood is 100 N?
A 7.7 kg mass is attached to a massless spring with spring constant k = 32.7 n/m . The system rests on a frictionless horizontal surface. If the spring is compressed by 8.6 cm, then released, what is the maximum velocity of the mass?
A small rocket for gathering weather data has a mass of 30 kg and generates 1500 N of thrust. On a windy day, the wind exerts a 20 N horizontal force on the rocket. If the rocket is launched straight up, what is the shape of its trajectory, and by how much has it been deflected sideways when it reaches a height of 1.0 km? Because the rocket goes much higher than this, assume there’s no significant mass loss during the first 1.0 km of flight.

A small box of mass m = 1.50 kg starts from rest and glides down a smooth, frictionless hill fromn a height h = 2.00 m to the base, where it meets a rough plank of mass M = 5.00 kg that is resting on the frictionless horizontal ground surface. Due to the friction between the box and the plank, its speed is reduced until, at a certain moment, it begins to move together with the plank as if they were a single object. Figure B2.
