A brick is dropped (zero initial speed) from the roof of a building. The brick strikes the ground in 2.5 s. You may ignore air resistance, so the brick is in free fall. How tall, in meters, is the building? what is the magnitude of the brick's velocity just before it reaches the ground? Sketch a,-t, vy-t, and y-t graphs for the motion of the brick.

Tired, you walk from your house to a local coffee shop to get an espresso. You average a speed of 2.4 m/s on your way there. After your espresso, you decide to run directly back to your starting point with an average speed of 5.6 m/s. Assume you spend 4 minutes at the coffee shop. If your average speed for this entire trip is 1.9 m/s, what is the distance between your house and the coffee shop?
Nerve impulses in a human body travel at a speed of about 100 m/s. Suppose a person accidentally steps barefoot on a pebble. About how much time does it take the nerve impulse to travel from the foot to the brain (in s)? Assume the person is 1.60 m tall and the nerve impulse travels at uniform speed.
A cart is given an initial velocity of 8.3 m/s and experiences a constant acceleration of 3.3 m/s?. What is the magnitude of the cart's displacement during the first 7 s of its motion?
Hello. I am working on a problem with motion. The questions asks me to calculate the maximum height (h1), total time (t2), and speed of a ball right before it hits the ground. The question states that A person is throwing a ball upward into the air with an initial speed Vo = 10m/s. Assume that the instant when the ball is released, the person's hand is at a height ho = 1.5m. The speed of the ball at its peak height is zero, and the question needs to be solved in ascending part and descending part. I don't understand how to solve for the maximum height. What is the correct formula to use and why? For other questions like this, I will be able to solve them if I know the formulas for the ascending of the ball and the descent of the ball as well as the explanation. Thank you. For the sake of the question, the ball is being thrown straight up.
If we wanted the balls final speed to be exactly 27.3m/s, from what height, hens (in meters), would we need to throw it with the same initial velocity?
Your roommate drops a tennis ball from a third-story balcony. It hits the sidewalk and bounces as high as the second story. Draw a motion diagram, using the particle model, showing the ball’s velocity vectors from the time it is released until it reaches the maximum height on its bounce.

A bike travels 6.53 x 103 m at 67.9 degrees North of East in a time of 2.56 x 103 seconds. The biker then has a drink for 1.23 x 103 seconds. She then rode a distance 6.05 x 103 m South in a time of 2.93 x 103 m seconds. She paused for 1.88 x 103 seconds, and it takes her back to her starting point. What was the magnitude of the average velocity of their entire ride?
The displacement of a particle is given by s = 4t³ - 60t² + 100t -58 where s is in feet and t is in seconds. Plot the displacement, velocity, and acceleration as functions of time for the first 13 seconds of motion. After you have made the plots, answer the questions. Questions: At t = 1.8 S= i fty = i ft/seca = i ft/ser sec, At t = 6.6 i S= fty = i ft/seca = i ft/se sec, Att = 9.8 sec, i fty = ft/seca = S = i ft/ser The velocity is zero when t = i sec and when t = sec
