Assume that a bowling ball, initially traviling at 12.0m/s,has 5 times the mass of a pin and that the pin goes off at 80* fromthe original direction of the ball.
A) Calculate the final speed of the pin,
B) the final speed of the ball,
C) and the angle throughwhich the ball was deflected. Assume the collision iselastic.
The force of the wind on the sails of a sailboat is 300 N north. The water exerts a force of 210 N east. If the boat (including crew) has a mass of 310 kg, illustrate what are the magnitude and direction of its acceleration?
A cannon fires a cannonball from the top of a wall at a speed of 25.58 m/s and an angle of 17.44 degrees from the horizontal. What is the horizontal distance from the wall where the fired cannonball hits the ground
Consider an elevator that is hanging from a strong cable. The elevator is initially at rest. It then accelerates upwards for 2 seconds, due to the cable pulling. It then then slows down, still moving upwards, until it comes to a stop. Pick out any..
Two particles each have a mass of 5.80 10-3 kg. One has a charge of +5.0 10-6 C, and the other has a charge of -5.0 10-6 C. They are initially held at rest at a distance of 0.70 m apart. Both are then released and accelerate toward each other. How fa..
