A Scientists want to place a 2600 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 2.2 times the radius of Mars above the surface of the planet. Here...
Consider the 620 N weight held by two cables. The left-hand cable had tension T and makes an angle of θ with the wall. The right-hand cable had tension 910 N and makes an angle of 26 ? with the ceiling...
A 1351.9 kg car is traveling at 22 m/s when the driver takes his foot off the gas pedal. It takes 4.2 s for the car to slow down to 20 m/s. How large is the net force slowing the car? Answer in units...
A force is applied to a 1.4 kg mass and produces 2.4 m/s2 acceleration. What acceleration would be produced by the same force applied to a 6.3 kg mass? Answer in units of m/s2.
I'm not sure how to solve for radial speed. The farthest I can get is solving for the circumference of the circle which is 2*pi*r or 2*3.14*22=138.2
I know that W=FXD but in that case that mean that the work done for this problem is 2 joules. Is that right?
I am struggling to solve this problem and i have tried to look it up on how to solve it and i'm clueless. I would appreciate some help solving this problem.
This is one of the questions on my review guide my teacher gave me and I have a test tomorrow and have no idea how to find the answer to this question! If someone could give the formula to find mass...
During a 4.70 s interval, a particle's coordinates change from x = 10.3 m, y = 4.60 m to x = 29.7 m, y = -4.6 m. Assuming the particle's velocity is constant, what will its coordinates be at the end...
