A rocket-powered hockey puck moves on a horizontal frictionless table. The following figure shows graphs of vx and Vy, the x- and y-components of the puck's velocity. The puck starts at the origin. a. In which direction is the puck moving at t=2s? Give your answer as an angle from the x-axis. b. How far from the origin is the puck at t=5s?

An object rolls off a tabletop with a horizontal velocity v0x = 2.1 m/s. The table is at a height y0 = 0.75 m, above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, its horizontal x-axis lying directly beneath the object’s trajectory, and its vertical y-axis pointing up.   A. How long, in seconds, is the object falling before it hits the floor?  B.How far, in meters, does the object land from the edge of the tabletop?  C. What is the vertical component of velocity, in meters per second, when the object hits the ground? Recall that the positive y-direction is upwards.  D. What is the magnitude of the velocity (it's speed) when it hits the floor?

A cannonball is fired from a height of 25 m above ground level, with an initial speed of 22.36 m/s and at an angle of 63.4⁰ above the horizontal. The cannonball lands at ground level. a. How long was the ball in the air (the “hang time")? b. How far does the cannonball travel horizontally? c. What is the final speed of the cannonball just before making contact with the ground?

An object rolls off a tabletop with a horizontal velocity Vox = 12 m/s. The table is at a height yo = 0.65 m above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, it’s horizontal x-axis lying directly beneath the objects trajectory, and it’s vertical y-axis pointing up. a. How long, in seconds, is the object falling before it hits the floor? b. What’s the horizontal distance, in meters from the edge of the tabletop to where the object lands? c. What is the vertical component of velocity, in meters per second, when the object hits the ground? d. What is the magnitude of velocity when it hits the floor?
