A bullet (m=0.005kg) moving at 500 m/s strikes and sticks in a block of wood (m=5kg). What is the final velocity of the wood/ bullet mass?   Before After mA 0.005kg 0.005kg VA 500 m/s ? mB 5 kg 5 kg VB 0 m/s ?

A 20 g ball of clay travelling west at 2.5 m/s collides with a 30 g ball of clay travelling south at 4.0 m/s. What are the speed and direction of the resulting 50 g of clay?

1. Two balls with mass mA = 3.0kg and mg = 2.0kg are initially moving towards each other with initial velocities as vai = 1.0m/s and Vai = -4.0m/s. If the collision between them is elastic, what is the Vai final velocities of the balls? Before Collision A VA Bi m, After Collision V Af A m, V.

A 10 gram bullet is fired from a gun and embeds itself into a 1.0 kg block of wood. After the collision the block of wood skids away at 4.0 m/s. What was the initial speed of the bullet?

A 330.0 g bird flying along at 8.10 m/s sees a 17.0 g insect heading straight toward it with a speed of 26.0 m/s. The bird opens its mouth wide and enjoys a nice lunch. What is the bird's speed (in m/s) immediately after swallowing?

4. In an elastic head-on collision, a 0.60 kg cart moving at 5.0 m/s [E] collides with a 0.80 kg cart moving at 2.0 m/s [W]. The collision is cushioned by a spring (k = 1,200 N/m). i. Determine the velocity of each cart after the collision. ii. Determine the maximum compression of the spring.

Two sumo wrestlers are in a match and at the start, they both lunge at each other.  When they hit each other they miraculously come to a stand still.  The first wrestler had a mass of 196 kg and was traveling at a velocity of 2.3 m/s at the instance of the collision.  a) If the second wrestler was traveling at 2.7 m/s at the moment of the collision, what was his mass in kg?

Pls help ASAP. Pls look at both images.

During the US Open, a 56 g tennis ball is hit at 12.0 m/s.  Considering, determine the maximum number of meters the ball will reach within 1.2 s.

1. A 200 g steel ball and a 400 g steel ball are hanging from equal length (L=0.5m) strings so that they are barely touching. The 200 g ball is pulled up so that the string makes a 45 degree angle with the vertical and then released. Assume that the collisions are elastic. a. What is the velocity of the 200 g ball just before it collides with the larger ball? b. What are the velocities of both of the balls just after the collision? c. To what height does each ball go after the collision? d. What angle does each string make at its maximum height?
