I added the force of friction on M1. (to the right)
My final answer makes sense to me in my mind but I am not sure if there is some kind of mistake or something that I am missing.
(am I correct to say that Nm3which acts on block M1 is m3a2?)
oh you i forgot that complimentary frictions must act on M1. brb will edit that into my solution.
also, for this example, you can assume that there is only friction between M1 and M2, nowhere else.
Homework Statement
1)What should F be so that m3accelerates upwards at 1 m/s2?

So I start by drawing FBD's for everything:
^^also, there is supposed to be a force of friction to the right on M1, I factored that into my...
ok, so what i did first is write the velocity and position for the dropped ball 2.00 seconds into its' "flight":
vf = -19.62 m/s (i choose up to be positive here)
xf = 36.4 m (above origin)
so now i guess they're in the"state" where they can be related using a relative equation
x12 = 0...
Homework Statement
1)A ball is dropped from the top of a 56.0 m-tall building. After 2.00 s, another ball is thrown upward from the ground. When the two balls pass the same point, they have the same speed. How fast was the upward-bound ball thrown?
2)You are riding an elevator with an...
Since relative acceleration is zero, there would only be one solution for t, at 0?
Makes no sense so I definitely did not construct the equation correctly
Homework Statement
An ocean liner approaches a peer at 20km/h. When the ocean liner is 10 km away, the captain sends a speedboat to the pier to pick up the harbour pilot, who will help dock the ocean liner. The speedboat takes 12 min to get to the pier.
a) How long would the speedboat take to...
