Base your answer on the information below and on your knowledge of
physics.
A cannonball with a mass of 1.0 kilogram is fired horizontally from a 500-kilogram cannon, initially at rest, on a horizontal, frictionless surface. The cannonball is acted on by an average force of 8.0 x 103 newtons for 1.0 x 10-1 second.
What is the magnitude of the change in momentum of the cannonball during firing?

An astronaut weighs 850 N on the Earth’s surface. When the astronaut lands on Planet X, she weighs 190 N. To the nearest tenth of a m/s2, what is the acceleration of gravity on Planet X? (hint: first find her mass!) An elevator car loaded with two passengers has a mass of 1200 kg. What tension must be applied by the elevator cable to give the car an acceleration of 1 m/s2 upward? Round your answer to the nearest newton....

Your friend is about to drive away after moving out and you notice that they left behind their basketball, so you decide to throw it at a 45 degree from the horizontal towards the truck. If the truck is 7.3 m away from you, at what speed must you throw the ball for it to make it into the truck? Assume you launch the ball at the same height as the truck bed. Report the value in m/s rounded to...

A force in the + x-direction with magnitude F(x) = 18.0 N - (0.530 N/m)x is applied to a 6.90 kg box that is sitting on the horizontal, frictionless surface of a frozen lake. F(x) is the only horizontal force on the box. If the box is initially at rest at x = 0, what is its speed after it has traveled 16.0 in? Express your answer to three significant figures and include the appropriate units.
