Actually I cannot figure out where I went wrong on the T1 equation to mess up the signs. Do I need to acknowledge that M1 will be the weight going up and M3 will be in the downward direction? I think that will give me the correct signs for T1? I am a little confused I must admit.

I figured it out. My T1 equation has reversed signs! Silly me. Thanks!

Homework Statement A box of mass m2=3.5 kg rests on a frictionless horizontal shelf and is attached by strings to bodes of masses m1 = 1.5 kg and m3 = 2.5kg. Both pulleys are frictionless and massless. The system is released from rest. After it is released, find (A) the acceleration of each...

Thanks.

I figured it out thanks for the help.

Homework Statement A projectile is fired into the air from the top of a 200-m cliff above a valley. It's initial velocity is 60 m/s at 60 degrees above the horizontal. Where does the projectile land? Homework Equations delta x = intial velocity of x * t delta y = -.5*g*t The...

I honestly am very confused at this point.

I get inital velocity = .5*g*t. I found that solution earlier but I do not understand how they get an angle from that information?

Homework Statement The range of a cannonball fired horizontally from a cliff is equal to the height of the cliff. What is the direction of the velocity vector of the projectile as it strikes the ground? (ignore air resistance) Homework Equations I attempted setting delta y = delta x...
