A blue puck with a mass of 4.30×10?2kg , sliding with a speed of 0.190m/s on a frictionless, horizontal air table, makes a perfectly elastic, head-on collision with a red puck with mass m, initially at rest. After the collision, the velocity of the blue puck is 3.0×10?2m/s in the same direction as its initial velocity.
Find the magnitude of the velocity of the red puck after the collision.
Find the direction of the velocity of the red puck after the collision.
Find the mass m of the red puck.

A new General Electric kitchen stove has a mass of 68kg and the dimensions. The stove comes with a warning that it can tip forward if the person stands or sits on oven door when it is open.
A typical power plant uses some fuel as the source of heat (QH) to drive a heat engine that does work (W) to drive a generator that is connected to the electrical grid. Inevitably, waste heat (QC) is dumped into a river or lake. Analysis of the pl..

On a hot summer day in the state of Washington while kayaking, I saw several swimmers jump from a railroad bridge into the Snohomish River below. The swimmers stepped off the bridge, and I estimated that they hit the water 1 s later.
At time t = 0, the hockey puck is sent sliding over a frozen lake, directly into a strong wind. Gives the velocity v of the puck versus time as puck moves along a single axis. (The time axis is marked in increments of 0.25 s.) At t = 2.8 s, what i..
