A space ship is stalled out in space. The turtle pilot takes a spacewalk to try and give the ship a push to get it started (Weird right?). The ship has a mass of 1,085-kg, and the pilot has a mass of 10.5-kg. a. If the pilot exerts a force of 87 N on the ship. What is the force that the ship exerts on the pilot? (2 pt)
b. What is the acceleration of the pilot? Show your work. (2 pt)
c. What is the acceleration of the ship? Show your work. (2 pt)

Acar tire rotates at a constant angular velocity of 3.5 rotations during a time interval of 0.75 seconds. what is the angular speed of the tire? in advance for any !

When a charged balloon sticks to a wall, the downward gravitational force is balanced by an upward static friction force. the normal force is provided by the electrical attraction between the charged balloon and the equal but oppositely charged polarization induced in the wall's molecules. if the mass of a balloon is 1.2 g, its coefficient of static friction with the wall is 0.71, and the average distance between the opposite charges is 0.80 mm, what minimum amount of charge must be placed on the balloon in order for it to stick to the wall? express your answer to two significant figures and include appropriate units.
