A steel ball is dropped onto a hard floor from a height of 1.75 m and rebounds to a height of 1.25 m. Use a coordinate system in which the vertical component of velocity is positive in the upwards direction. Calculate its velocity, in meters per second, just before it strikes the floor. Calculate its average acceleration, in meters per second squared, during its contact with the floor if that contact lasts 0.0800 ms (8.00 × 10-5 s).

Which of the following is INCORRECT about projectile motion with the same initial and final elevations? a. The total time of flight is twice the time to reach the maximum height. b. The magnitude of the acceleration at the maximum height is 9.8 m/s2. c. At its maximum height, the velocity of the projectile is zero. d. Only the vertical component of the motion is accelerating.
Use a graphing utility to obtain the path of a projectile launched from the ground (h = 0) at the specified values of θ = 35°, v0 = 300 feet per second. In the exercise, use the graph to determine the maximum height and the time at which the projectile reaches its maximum height. Also use the graph to determine the range of the projectile and the time it hits the ground. Round all answers to the nearest tenth.

Two particles move along an x axis.The position of particle 1 is given by x = 6.00t2 + 3.00t + 2.00 (in meters and seconds); the acceleration of particle 2 is given by -8.00t (in meters per second squared and seconds) and, at t = 0, its velocity is 20 m/s.When the velocities of the particles match, what is their velocity?
In a baseball game the initial speed of a ball was measured to be 43 m/s. The batter hits and send the ball in the opposite direction with a speed of 51 m/s. Assuming the flight trajectories are horizontal and linear; and the bat-ball contact time is 1.0 ms, find the average acceleration of the ball.
