Shown in the figure is a ball with mass, m, and initial speed, v, hitting the ground at an angle. The ball bounces off the ground and leaves with the same speed as it initially had and makes an angle with the ground as shown in the figure. What is the impulse by the ground on the ball in unit vector notation? OO + 2mv cos(0) û O0+ 0 g 2mv cos(O) € + 2mv sin(0) ☺ 00 € +...

Object A of mass M is initially at rest on a flat, smooth
frictionless surface. Object B, which has twice the mass of A, is
traveling with speed V before it collides elastically with A.
Immediately after the collision, both objects move off at angles
(theta)>0 with respect to the original direction of B. Calculate
the value of the angle.
[Hint: Note that the collision is elastic.] .

As shown in the figure, a wooden ball with mass m, is initially at rest on a horizontal, frictionless table. A second wooden ball with mass m, moving with a speed 2.00 m/s, collides with my. Assume m, moves initially along the +x-axis. After the collision, m, moves with speed 1.00 m/s at an angle of 0 = 52.0° to the positive x-axis. (Assume me = 0.200 kg and m, = 0.300 kg.) Figure b: After the collision Before the...

HW-65 problem concerns three collision experiments performed on a frictionless surface with Tiers A and B, with masses mA and mg, respectively. In all three experiments, the instantaneous seeds of gliders A and B are initially w, and 0, respectively. If not given enough information is given to answer any of the parts, state so explicitly. a. In experiment 1, the track is level, and the gliders are repelled by magnets, so they do not come into contact. At time...

4. Energy and Momentum for 15 points: A 200 gram lab cart is initially at rest on top of a 50 cm ramp, as shown. Note that the wheels are very light and the axle has no friction in it. You push the cart as it moves through a distance of 20 cm with a constant force of 10N in a direction oriented 20 degrees below horizontal. After you stop pushing on the cart, it encounters a ramp, and rolls...

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...

1) Why is there a different equation for elastic vs inelastic collisions? Are they really different? 5) If the first car does not go through either photogate after collision, what will its velocity essentially be? The conservation of momentum is a fundamental law in classical mechanics. It states that the total momentum of a system at the initial condition and ending conditions must be equivalent or p. - P. This can be modeled by studying the effect of objects in...
