The force exerted by the wind on the sails of a sailboat is
Fsail = 300 N north. The water exerts a force
of Fkeel = 240 N east. If the boat (including
its crew) has a mass of 260 kg, what are the magnitude and
direction of its acceleration?

Scientists want to place a 2600 kg satellite in orbit around Mars. They plan to have the satellite orbit at a speed of 2482 m/s in a perfectly circular orbit. Here is some information that may help solve this problem: m_mars = 4191 times 10^23 kg r_mars 3.397 times 10^6 m G = 6.67428 times 10^-11 N-m^2/kg^2 What radius should the satellite move at in its orbit? (Measured from the center of Mars.) What is the force of attraction between...

please help!
The figure below shows a metal ball with a mass of 2.84 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v - 10.0 ms, and the angle its path makes with the wall is 8 - 60.0° as shown. (Because we are analyzing the motion of the ball over a very short time just before and after Impact, you may safely ignore the effect of gravity on the...
