ohhhkk thanks...and for the conservation energy is 1/2m1v^2 + 1/2 M2 V^2 = M1g h sin(X) - (mu)M2g hcos(X)- M2gh ??

no there is no R or I is given and only the mass of the pulley is given which is making me confuse. and the part 2 of the quest with the conservation of the energy, I really do not have any idea about that how we do that can you please help me out with that??...:)

Homework Statement 1. For the system shown below use Newton’s Laws to clearly derive an expression for the acceleration of each mass and the tensions in the cord. The coefficient of friction between m1 and the incline is 0.100. The mass m1 is 3.00 kg, m2 = 8.00 kg, and θ = 35.0°. The...

I tried by getting the time first y = 1/2 gt^2 but I am lost after that can anyone please help me out...

a cannonball is fired with initial velocity v0 at an angle 30 above the horizontal from the height of 40m above the ground. the projection strikes the ground with a speed of 1.2*v0. find v0

Homework Statement Car A is traveling east at 20m/s toward the intersection, car B from rest 40 m North of the intersection and moves south steadily gaining speed at 2.0 m/s^2. six second after A crosses the intersection find 1) position of B relative to A 2) the velocity of B relative to A...

I got the answer tan(30)=100/x solving the equation for 'x' we get X= 173 km

This is what i think the triangle should be like...B to the east (Right) of ship and A to the south 30 degrees down.

Homework Statement You are the navigator of a ship at sea. You receive radio signal from 2 transmitters A & B which are 100 Km apart, one due south of other. The direction finder shows you that transmitter A is at a heading of 30 degree south of east from the ship. while transmitter B is due...
