(c7p50) A 900- kg car collides with a 1400- kg car that was initially at rest at the origin of an x-y coordinate system. After the collision, the lighter car moves at 30.0 km/h in a direction of 30 o with respect to the positive x axis. The heavier car moves at 33 km/h at -46 o with respect to the positive x axis. What was the initial speed of the lighter car (in km/h)?
What was the initial direction (as measured counterclockwise from the x-axis? (numeric)

An unstable nucleus of mass 1.7 ✕ 10−26 kg, initially at rest at the origin of a coordinate system, disintegrates into three particles. One particle, having a mass of m1 = 1.0 ✕ 10−27 kg, moves in the positive y-direction with speed v1 = 5.0 ✕ 106 m/s. Another particle, of mass m2 = 8.0 ✕ 10−27 kg, moves in the positive x-direction with speed v2 = 3.8 ✕ 106 m/s. Find the magnitude and direction of the velocity of...

A particle with mass 4.0 kg is initially at rest at the origin (x=0). It then moves along the x-axis acted on by a force F(x)=18.0-2.0x2, where F is in Newtons if x is expressed in meters. Find the kinetic energy of the particle when it reaches x=3 m.

A car with a mass of 980 kg is initially traveling east toward
an intersection with a speed of vc = 20.9 m/s and a 1500 kg pickup
is traveling north toward the same intersection. The car and truck
collide at the intersection and stick together. After the
collision, the wreckage (car and truck) moves off in a direction of
44.0° above the x-axis. Determine the initial speed of the truck
and the final speed of the wreckage in meters...
