Yeah I did do it the way you told me at first and got a number that made absolutely no sense but the way you just illustrated makes more sense....thank you

Help. Physics
I used the equation m1vf1 + m2vf2 = m1vi1 + m2vi2 and got a vf of 1.52m/s I then plugged that into the equation t=d/v => t=20.5/1.52 and got 13.5s

A sled slides along a horizontal surface on which the coefficient of kinetic friction is 0.30. Its velocity at point A is 7.6 m/s and at point B is 4.0 m/s. Use the impulse-momentum theorem to find how long (in s) the sled takes to travel from A to B. Assume that the local acc...

A 2.5 kg block is launched up a ramp at 9.0 m/s. If the ramp is 35 degrees above the horizontal and the coefficient of static friction is 0.60, while the coefficient of kinetic friction is 0.25. a. How far does the block go up the ramp from its starting point? b. What speed do...

Thanks but how do you do it?

In an amusement ride, fun seeking people enter a 7.4 meter diameter cylinder and stand up against the wall. The cylinder spins fast enough so that when the bottom drops down 2 meters, the people remain pinned to the wall. The cylinder continues to rotate for awhile but then s...
