An elevator starts from rest and moves upward, accelerating at a rate of 1.2 m/s2 until it reaches a speed of 7.8 m/s, which it then maintains. Two seconds after the elevator begins to move, a man standing 12 m above the initial position of the top of the elevator throws a ball upward with an initial velocity of 20 m/s. Determine when the ball will hit the elevator.
While curling, you push a rock for 2.50 m and release it when it has a speed of 1.60 m/s. It continues to slide at constant speed for 1.10 s and then hits a rough patch of ice. It finally comes to rest 7.40 m from where it was released.
What was the curling rock's magnitude of acceleration after it hit the patch of rough ice?

- A distance of 90 meters separates two jetskis at Virginia Beach. Starting at rest, the jetskis accelerate at a constant rate of 0.7 m/s² towards each other. Starting at a midpoint between the two jetskis, a porpoise is seen swimming from one jetski to the other at a constant speed of 18 m/s. The porpoise continues swimming back and forth between the jetskis until they crash together. What is the total distance the porpoise travelled? 158.7 You are given the initial velocity Vo, acceleration a and the distance Ay. You have the speed of the porpoise, so you are looking for time.

In a coordinate system with north being the positive x direction, the scooter's motion is towards the north. 1)What was the scooter's average speed, in meters per second, during this period? 2)What was the scooter's displacement, in meters, in the northern direction during this period? 3)What was the scooter's average velocity, in meters per second, in the northern direction during this period ? 4)A second scooter begins traveling from rest at t0=0.0s and stops at t′f=176s.

Neglect air resistance and assume that the rocket stays close enough to the ground that the acceleration due to gravity (after the rocket engine stops) is given by g. a) Find the maximum height, H, that the rocket reaches above the ground. b) If the rocket's net acceleration, B, is equal to 1.0g, find an expression for the total time, Tmax, that the rocket is in the air (i.e. from liftoff until it hits the ground) in terms of T1. You do not need to solve your expression numerically but simplify it as much as possible.arrow_forwardA dog and her handler are at rest, and are facing each other at a distance of 40.0 m.
