1. A cannon fires a cannonball at an angle of 30° above horizontal. The initial velocity of the cannonball is 40 m/s. Assume the coordinate system in which x is horizontal and y is vertical. (a) What is the x-component of the initial velocity? '40 % cos ao (b) What is the y-component of the initial velocity? (c) Gravity causes a constant acceleration of 9.81 m/s. In what direction is this acceleration? (d) What affect will this acceleration have on...

A circus act consists of a performer (a "human cannonball") being launched from a cannon into a net at the other end of the stage. The performer (mass 60 kg) leaves the cannon at a speed of 25 m/s at an angle of 30o above horizontal. She comes out of the cannon at a height of 2 meters above the ground and lands in the net at a horizontal distance of 45 meters away from the launch point. Let +x...

At a circus, a clown is being shot out of a cannon. This is a good thing because clowns are terrifying. The cannon’s barrel makes an angle of 35 degrees with the ground and the initial velocity has magnitude 10.4 m/s. The end of the barrel is 1.0 m above the ground. A 1.0 m thick mattress, with sides 2.0 m long, is placed so its closest edge is a horizontal distance of 10.0 m from the end of the...

You pull a box 45 degrees from the horizontal with 50N force. The box is moving at a constant velocity. How much force is done by the kinetic friction? For any problems with tensions, pushing or moving boxes, draw out a free body diagram. You only want the kinetic frictional force which is only on the x direction, so let's sum up the forces in the x Fr=maio (28)

Newton’s Cannon Imagine you fired a cannonball such that the range of that ball was slightly longer than the radius of the Earth. As that ball fell back down, it would miss the ground and continue to fall. If we can ignore any air resistance or collisions with other objects, then we can say the ball would continue to fall forever, just missing the ground, and thus be in orbit. Assume all orbits here are perfectly circular and pretend that...

fast was Stan going at the time of impact?
Stan the Man, from the local circus, was a human cannon ball. While practicing one day, he was shot out of a cannon and into a canyon and subsequently died. It is believed it was murder but suicide cannot be ruled out, yet. Here are the facts of the case One afternoon, Stan climbed into the cannon for reasons we do not know. According to...

A block (425‐kg) is sitting on a ramp, which is angled 25.0‐degrees above the horizontal. A rope pulls up the ramp with 275N and another rope pulls horizontally at 175N. The coefficient of static friction is 0.855. The coefficient of kinetic friction is 0.655. a. Draw a free‐body diagram for this case. Make sure to indicate a coordinate system. b. Write out Newton’s 2nd Laws, once for each dimension. c .Determine the acceleration of the block. d. Pick one force from your free‐body...
