12.0 ft/s 33° A billiard ball hits a bumper with the velocity shown. The coefficient of restitution between the ball and the wall is 0.82. What is the speed of the ball the instant it leaves the wall? (include units with answer)

1. In a practice session, Iris hits a ball horizontally with a speed of 36 m/s from a height of 3.1 m. The ball travels until it hits the ground. a. Determine the time the ball is in the air. b. Determine the horizontal distance traveled by the ball. c. Calculate the ball’s velocity as it hits the ground.

If the stone had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, then compare their impact velocities.  a)The impact velocity when throwing a stone above horizontal will be more than the case when throwing a stone below horizontal. b The impact velocities of the two situations will be the same.  c More information is needed to conclude the relative strength of impact velocities. d).The impact velocity when throwing a stone above horizontal will be less than the case when throwing a stone below horizontal.  which option is correct

→ An ion's position vector is initially = 7.01 - 7.01 + 9.0k, and 5.0 s later it is = 5.01 + 6.0 - 5.0k, all in meters. What was its the 5.0 s? (Express your answer in vector form.) V avg Additional Materials m/s Algebra-Squareroots & Squares avg during
