Question

iPad 3:59 PM * 48%. 115:33:08 Exit 1 A rifle is fired straight up, and the bullet leaves the rifle with an initial velocity magnitude of 525 m/s. After 4.15 s, the velocity is 482 m/s. At what rate (in m/s2) is the bullet decelerated? (Recall that a negative sign denotes negative acceleration, or deceleration.) Enter answer 2 A rock thrown straight up climbs for 3.50 s, then falls to the ground. Neglecting air resistance, with what velocity (in m/s) did the rock strike the ground? Enter answer 3. An object is observed to fall from a bridge, striking the water below 1.36 s later. With what velocity (in m/s) did it strike the water? Enter answer 4. A ball dropped from a window strikes the ground 3.77 s later. How high is the window above the ground in meters? Enter answer 5. A balls rolls horizontally off from a table with a height of 0.75 m while traveling at a speed of 2.35 m/s. How far will the ball travel horizontally from the end of the table before striking the ground? Enter answer Submit
