1. A ball with a mass of 2.00 kg and an initial velocity of ?⃗1 = 30.0m/s ?̂ collides with another ball of mass 1 kg which is initially sitting still. After the collision, the second mass has a velocity of ?⃗2f = 25.0m/s ?̂. What is the velocity of the first mass after the collision? 2. Two billiard balls with identical masses of 1 kg move toward each other. The initial velocity of ball 1 is +30 cm/s and...

A solid uniform sphere of radius 0.76 cm and a mass of 0.87 kg is held against a spring compressed a distance of 6.0 cm from its resting length. After release, the sphere leaves the spring and rolls down the flat, horizontal table with a translational velocity of 3.9 m/s. a) What is the force constant of the spring? b) If the ball then rolls up a ramp inclined at 22 degrees, how far along the ramp does it travel?

A mass m = 1 kg slides down a θ = 30◦ inclined plane from a
height of 5 m. At the bottom of the incline, it collides with
another mass M = 3 kg, and the latter is initially at rest as shown
in Fig. 3. The surface to the right of the inclined plane on which
the 3 kg (green) mass sits is horizontal.
(a) The inclined surface is frictionless. Conserve energy to
find the velocity of the...

5. Ball 1 has a mass of 2.0 kg and is suspended with a 3.0 m rope from a post so that the ball is stationary. Ball 2 has a mass of 4.0 kg and is tied to another rope. The second rope also measures 3.0 m but is held at a 60.0° angle, as shown in Figure 7. When ball 2 is released, it collides, head-on, with ball I in an elastic collision. (a) Calculate the speed of each...

In the figure, a solid cylinder of radius 6.1 cm and mass 20 kg starts from rest and rolls without slipping a distance L = 7.4 m down a roof that is inclined at angle θ = 25°. (a) What is the angular speed of the cylinder about its center as it leaves the roof? (b) The roof's edge is at height H = 3.9 m. How far horizontally from the roof's edge does the cylinder hit the level ground?

Elastic Collision Question 8 A 2 kg ball initially at rest rolls down a 30-degree inclined plane from a height of 4 meters (assume kinetic and rolling friction are negligible). A 2 kg box initially at rest slides down a 30-degree directionless inclined plane from a height of 4 meters. How do the velocities of the ball and the box compare when they both reach the bottom of their respective inclined planes?...

m d[m] Problem 1 [20 points) A box of mass m = 6 kg slides down an inclined ramp of length d = 2 m as shown in the Figure. The box starts with initial speed 2 m/s at height h = 1 m from the bottom of the ramp. A constant friction force f = 3 N is applied to the box when sliding h[m] down the ramp. Consider the box of mass m, as your system. a) [5...
