One seemingly easy problem. Please help! due soon! Homework Statement An astronaut of mass 77.0 kg is taking a space walk to work on the International Space Station. Because of a malfunction with the booster rockets on his spacesuit, he finds himself drifting away from the station with a...

Please pardon my stupidity. How would I break up T1 and T2 into components? My first impulse was to do 350costheta and 350sintheta for each tension force and its respective theta but that's obviously not the way to go. I also figured that if the system was in equilibrium. F1total + F2total +...

Homework Statement A bag of cement of weight 350 N hangs from three wires as suggested in the figure below. Two of the wires make angles θ1 = 50.0° and θ2 = 27.0° with the horizontal. Assuming the system is in equilibrium, find the tensions in the wires. Homework Equations Newton's...

The astronaut orbiting the Earth in Figure P4.32 is preparing to dock with a Westar VI satellite. The satellite is in a circular orbit 470. km above the Earth's surface, where the free-fall acceleration (centripetal acceleration) is 8.19 m/s2. Take the radius of the Earth as 6370 km...

Sorry I wasnt sure If I could use delta y = 1.05 because that isn't the max height of the parabola and delta x = 13 because the full length of the parabola isn't 13. Ok so based on that information I derived that Ax = 0 Vxi = xcos43 Vxf = xcos43 deltax = 13 tx = ty Ay = -9.81 Vyi...

I'm not sure how to apply the constant acceleration kinematic formulas because I only have information for two of the variables for each direction. For instance I have for the x (horizontal) direction: Ax = 0 Vxi = xcos43 and for the y: Ay = -9.81 Vyi = xsin43 If I had delta x or y...

Homework Statement A basketball player who is 2.0 m tall is standing on the floor L = 13.0 m from the basket. If he shoots the ball at a 43.0deg angle with the horizontal, at what initial speed must he throw so that the ball goes through the hoop without striking the backboard? The...

Yessiree. I think it's webassign but I guess I can skip this problem it's for extra credit.

131 m/s^2 in the upward direction to compensate for g, which is incorrect according to Webassign

I have two problems. I have filled in most of the information that is asked but I can't seem to figure out a part for each problem. Please Help. Problem 1: Homework Statement At a NASA research center free-fall research is performed by dropping experiment packages from the top of an...

Oh i knew that...lol sorry I was in a rush to go to class

2.9t^3 dh/dt = 5.8t^2 V-heli at 1.80 sec = 18.8 m/s = Vi-package which Webassign will not accept. please help and thanks for the quick reply!

Homework Statement The height of a helicopter above the ground is given by h=2.90t^3, where h is in meters and t is in seconds. After 1.80 s, the helicopter releases a small mailbag. Assume the upward direction is positive and the downward direction is negative. A) what is the velocity of...

Blurg! Webassign will not take my answers. Any other suggestions?
