Hi, I think I posted this in the wrong place, so im posting it here. I'm taking Physics w/ cal 1, and Im having problems solving a couple of question, I was hoping some one could help, I would appreciated it.. 1) block of mass m1=8kg is connected over an idead (masless and frictionless) pulley to block 2, of a mass m2=4kg. The magnitude of blocks acceleration is 3 m/s^2 and the angle of incline Theta=30 deg. a) find the coefficient of the kinetic friction between block 2 and the plane of the incline. b) what is the magnitude of the tension in the rope. and also this problem which is projectile motion - 2) Projectile is fired from the top of a 40m tower at an angle of 60 deg above the horizontal hits the ground at the point 100m from the base of the tower. a) find the speed at which the stone was thrown. b) find the speed of the stone just before it hits the ground. c)find the time at which the projectile hits the ground. d) find the maximum height. for a) i got 35 m/s Thank You.
