    How to Determine the Velocity of Block A with Pulley Masses Included?

    Homework Statement Block A has a mass of 3 kg, and block B has a mass of 8 kg. Determine the speed of block A if it moves upwards 2 meters, starting from rest. I can solve the problem pretty easily if the mass and radius of each of the pulleys is neglected. However, if they are not neglected...

    At what altitude should lunar lander's 30,000 N rocket fire to land safely at 1 m/s?

    yea, that doesn't work

    At what altitude should lunar lander's 30,000 N rocket fire to land safely at 1 m/s?

    Would I just solve for either x_1 or x_2 ?

    At what altitude should lunar lander's 30,000 N rocket fire to land safely at 1 m/s?

    I'm still confused on how I would find the altitude where the thrusters were fist turned on?

    At what altitude should lunar lander's 30,000 N rocket fire to land safely at 1 m/s?

    Are we talking about the equation: v=v(initial) + a*t ?

    At what altitude should lunar lander's 30,000 N rocket fire to land safely at 1 m/s?

    From my updated understanding of the problem, what's basically going to happen is: Neglecting the curvature of the moon the problem is basically this right? 1) The lander starts to fall starting at 30km more or less vertically towards the surface 2) He is going to pick up speed while doing this...

    At what altitude should lunar lander's 30,000 N rocket fire to land safely at 1 m/s?

    1. I have a physics problem that I am having trouble understanding. Here it is: Your lunar lander (with fuel and crew) has a mass of 14,700 kg. It is initially in a circular orbit around the Moon (i.e. Viy = 0 m/s) at an altitude of 30 km above the lunar surface. To land on the Moon, you...
