Calculate the magnitude of the linear momentum for the following cases: a 15.0-g bullet moving with a speed of 300 m/s.

A $300$ g bird flying along at $6.1$ m/s sees a $10$g insect heading straight toward it with a speed of $26$ m/s. The bird opens its mouth wide and swallows the insect. What is the bird's speed immediately after swallowing?

(A) Evaluate the discriminant and (B) determine the number and type of solutions to each equation. -6d^2 + 9d = 2

Two identical 1350-kg automobiles A and B are at rest with their brakes released when B is struck by a 5400-kg truck C that is moving to the left at 8 km/h. A second collision then occurs when B strikes A. Assuming the first collision is perfectly plastic and the second collision is perfectly elastic, determine the velocities of the three vehicles just after the second collision.

A $15.0\ \mathrm{g}$ rubber bullet hits a wall with a speed of $150\ \mathrm{m/ s}$. If the bullet bounces straight back with a speed of $120\ \mathrm{m/ s}$, what is the change in momentum of the bullet?

Calculate the linear momentum for a 75.0 kg sprinter with a velocity of 10.0 m/s southwest.

When you stand at rest on a pair of bathroom scales, the reading on each scale:
a. add up to equal your weight
b. equals your weight
c. is half your weight

A tennis player receives a shot with the ball (0.060 0 kg) traveling horizontally at 50.0 m/s and returns the shot with the ball traveling horizontally at 40.0 m/s in the opposite direction. What is the impulse delivered to the ball by the racket?

Two arrows are fired horizontally with the same speed of 30.0 m/s. Each arrow has a mass of 0.100 kg. One is fired due east and the other due south. Find the magnitude and direction of the total momentum of this two-arrow system . Specify the direction with respect to due east.

If you free the cork in a highly pressurized champagne bottle, the resulting launch of the cork will, in principle, cause the bottle to recoil. A filled champagne bottle has a mass of 1.8 kg. The cork has a mass of 7.5 g and is launched at 20 m / s. If the bottle could move freely, with what speed would it recoil? Is this something you are likely to notice?

A ball of mass 0.150 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.960 m. What impulse was given to the ball by the floor?

A 0.10 kg ball of dough is thrown straight up into the air with an initial speed of 15 m/s. Find the momentum of the ball of dough halfway to its maximum height on the way up.

A $2.00-\mathrm{kg}$ aluminum block and a $6.00-\mathrm{kg}$ copper block are connected by a light string over a frictionless pulley. They sit on a steel surface, where $\theta=$ $30.0^{\circ}$. When they are released from rest, will they start to move? If so, determine
(a) their acceleration\

The electric motor of a model train accelerates the train from rest to 0.620 m/s in 21.0 ms. The total mass of the train is 875 g. Find the average power delivered to the train during its acceleration.
