A mortar- style firework is launched from a vertical tube with a speed of 70.0 m/s. What is the highest height (in m) it reaches? part 2 - if the firework was a dud, and falls back to the ground, what is it's speed (in m/s) when it reaches the ground?
1. In 1992, a 14-kg meteorite struck a car in Peekskill, NY, leaving a 20-cm-deep dent in the trunk. If the meteorite was moving at 500 m/s before striking the car, what was the magnitude of its acceleration while stopping?
The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.00 s to a final velocity of 2.05 m/s, at which point the brakes are released. (a) What was its initial speed (in m/s), just before the brakes were applied? i have tried so many ways to solve this and i cant please explain
I've been moonwalking for hours, and I'm getting tired. Explain why, as I come to a stop, my velocity is increasing while my speed is decreasing.
here is my problem, I need help: One simple model for a person running the 100 mm dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.1 m/sm/s in 2.64 ss , what will be his total time? Express your answer in seconds.
From rest, the cheetah can accelerate at 8.8 m/s2 and reach a top speed of 30 m/s (108 km/h)! It can maintain this maximum speed over a distance of about 400 meters before it needs to stop.On the other hand, the Thomson’s gazelle has a top speed of 70 km/h, which is less than the cheetah’s, but it can maintain this top speed for a while as well. From rest, the gazelle can accelerate at 4.5 m/s2 to reach its top speed. When a cheetah goes after a gazelle, success or failure is a simple matter of kinematics: you will determine if the cheetah’s high speed is enough to allow it to reach its prey before it runs out of steam (or time).You will apply basic kinematics and simple assumptions to determine how a chase can play out. The Scene:A cheetah has spotted a gazelle. At the same instant the cheetah leaps into action, the gazelle has spotted him and starts heading directly away.Q1. After what total distance from rest must the cheetah stop? (clearly show calculations and substitutions) Q2.…

SpaceX plans to transport humans to Mars, but experienced a few rocket failures while on initial tests. So suppose the rocket to Mars (without people on board - another test flight) liftoffs from earth, from rest, with an acceleration of 52.5 m/s2. Unfortunately, after 7.80 s, the rocket experiences a failure and shuts off. It then continues to coast upward (with no appreciable air resistance). What is the maximum height the rocket reaches above the surface?
A frustrated physics student throws her physics text straight up with a speed of 15 m/s from a 50 m high bridge. How much time would it take to reach the water? Neglect friction. A Honda Civic travels in a straight line along a road. Its distance x from a stop sign is given as a function of time t by the equation x (t) = at^2 -bt^3, where a = 1.50 m/s^2 and b = 0.05 m/s^3. What is the instantaneous velocity of the car at t = 5 s? At what angle does the force F, where Fx = 6.23N and Fy = – 2.38N, makes with the positive x-axis?
A woodpecker’s brain is specially protected from large decelerations by tendon-like attachments inside the skull. While pecking on a tree, the woodpecker’s head comes to a stop from an initial velocity of 0.600 m/s in a distance of only 2.00 mm. (a) Find the acceleration in m/s^2 and in multiples of g (g=9.80m/s^2). (b) Calculate the stopping time.
When one person launched a model rocket straight upwards, it will accelerate at 3.7g(g=9.81m/s^2) for 4.1 seconds. Then the rocket will burn out(ignore air friction).What is the maximum height the rocket will reach? And what will the time from launch until it returns to the ground?
