A block of mass m slides at velocity vo across a horizontal frictionless surface toward a large curved movable ramp of mass 3m as shown in Figure 1. The ramp, initially at rest, also can move without friction and has a...
Yea we are just supposed to ignore gravity's effect during the acceleration phase and assume it doesn't start until free fall phase. It sounds dumb i know, but maybe when my instructor wrote it he thought the given acceleration has accounted for it's effect? idk, but yea it's still at 60º at the...

A rocket is launched and accelerates for 2 seconds with an acceleration a = 2t + 4t3 at 60º wrt the horizontal, it then "coasts" until impact at the same altitude which it was launched from.
Find a) V at t=2s
b) Max Height
c) Impact...
I have the volume at 59.5t, so the rate of change in volume would be 59.5 cm/s. But I don't know what relation to use to relate this volume to mass? Any help would be much appreciated :)
