1 2 3 00 00 Diagram is snapshot before collision. Mass of each boxcar = 10,000 kg. Refer to the illustration of three boxcars, above. The Boxcar 1 moves to the right at speed v1 = 5.4 m/s. Boxcars 2 and 3 are initially at rest. The total momentum before interaction is 198450 kg m m2/s2 63000 kg m/s 54000 kg m/s 189000 kg m/s Refer to the illustration of three boxcars, above. The Boxcar 1 moves to the right...

Given the formula of the kinetic energy of a particle m
with
speed v:
KE = 1⁄2mv2 ,
and the formula of the gravitational potential energy:
PE = -GMEm/R,
where G is gravitational constant and ME and R=6378 km are the
mass and the radius of Earth. Now the particle is shot from Earth
surface to space. Find the minimum required initial speed for this
particle to completely escape the influence of Earth gravity (i.e.
PE=0). Notice that the gravitational...

A block (6 kg) starts from rest and slides down a frictionless ramp #1 of height 6 m. The block then slides a horizontal distance of 1 m on a rough surface with kinetic coefficient of friction μk = 0.5. Next, it slides back up another frictionless ramp #2. Find the following numerical energy values: 1.Initial gravitational potential energy on Ramp #1: U1G = J 2.Kinetic energy at bottom of Ramp #1 before traveling across the rough surface: K =...
