In a room where g = 9.81 m/s2, a hockey puck slides off the edge of...
A hockey puck slides off the edge of a table with an initial velocity of 29.5 m/s and experiences no air resistance. The height of the tabletop above the ground is 2.00 m. What is the angle below the horizontal of the velocity of the puck just before it hits the ground?
Ruestion 10 6 po A hockey puck Slides off the edge of a table at point A with an initial velocity of 25 m/s and experiences no ale resistance. The height of the tabletop above the ground is 2.6 m. What is the speed (not the velocity) of the puck just before it touches the ground?
a). Suppose a hockey puck slides down a frictionless ramp with an acceleration of 4.00 m/s2. What angle does the ramp make with respect to the horizontal? ____ degree b).If the ramp has a length of 5.80 m, how long does it take the puck to reach the bottom? _____ s c). Now suppose the mass of the puck is doubled. What's the puck's new acceleration down the ramp? _____ m/s^2
If an air hockey pusher (120g) freely slides on the table at 1 m/s and hits a sitting puck (25g), what will be the speeds of the puck and pusher if the collision is perfectly elastic? Please provide explanation. Thank you
An 160.0 g hockey puck slides along an essentially frictionless ice rink with speed 4.70 m/s. A hockey player uses her stick to do –1.20 J of work on the puck. What is the puck's speed after she has done this work? A. 0 m/s B. 2.66 m/s C. 3.50 m/s D. 4.53 m/s
A stone is thrown horizontally with an initial speed of 10 m/s from the edge of a cliff. A stopwatch measures the stone's trajectory time from the top of the cliff to the bottom to be 4.3 s. What is the height of the cliff if air resistance is negligibly small?
A physics book slides off a horizontal tabletop with a speed of 3.5 m/s. It strikes the floor in 0.350 s. Ignore air resistance. Use g = 10 m/s2. Find: a. The horizontal and vertical components of the velocity when the book leaves the table. b. The height of the tabletop above the floor (how far does it travel vertically?). c. The horizontal distance from the edge of the table to the point where the book strikes the floor (how...

030 (part 1 of 3) 3.0 points A block starts at rest and slides down a fric- tionless track. It leaves the track horizontally, flies through the air, and subsequently strikes the ground 521 g What is the speed of the block when it leaves the track? The acceleration of gravity is 9.81 m/s2. Answer in units of m/s. 031 (part 2 of 3) 3.0 points What horizontal distance does the block travel in the air? Answer in units of...
(Problem 2/10 from Meriam and Kraige Dynamics) 60 m A ball is thrown vertically up with a velocity of 36 m/s at the edge of a 60 m cliffa. Neglect air resistance and take the downward acceleration to be 9.81 m/s2, calculate: (a) the height h to which the ball rises; hNumber (b) the total time t after release for the ball to reach the bottom of the clioff tNumber (Problem 2/10 from Meriam and Kraige Dynamics) 60 m A...
