A ball with a mass of 50 g is traveling at 25 m/s bounced off a brick wall and rebounded at 20 m/s. If a high speed camera was able to record the event and that the ball is known to have been in contact with the wall for 3.50 ms, what is the magnitude of the average acceleration of the ball during this time interval?

Nerve impulses travel at different speeds, depending on the type of fiber through which they move. In a scenario, the impulses for touch traveled at 57.3 m/s, while those registering for pain moved at 0.82 m/s. If a person stubs his toe, find the time delay between the pain and touch impulses. Assume that his brain is 1.60 m from his toe and that the impulse travels directly from toe to brain. Express your answer in seconds. Hint: Always take the positive value. Time difference is synonymous to time delay.
An initially motionless test car is accelerated uniformly to 135 km/hr in 8.08 seconds before striking a simulated deer. The car is in contact with the faux fawn for seconds, after which the car is measured to be traveling at 87.5 km/hr. What is the magnitude of the average acceleration of the car during the collision?

I am doing a free-fall experiment for Physics and I need to make a velocity vs. time graph using the average value of the final velocity. Do you know how I would be able to find the values for the velocity vs. time graph? The average value of the final velocity is 6.21954 m/s. It is question #9.
High-speed motion pictures (3500 frames/second) of a jumping 230 μg flea yielded the data to plot the flea's acceleration as a function of time as shown in the figure ( Figure 1). (See "The Flying Leap of the Flea," by M. Rothschild et al. in the November 1973 Scientific American.) This flea was about 2 mm long and jumped at a nearly vertical takeoff angle. Use the measurements shown on the graph to answer the questions. Figure alg 150 100 50 0 0 0.5 1.0 1.5 Part E Use the graph to find the flea's maximum speed.

A spaceship is traveling at a velocity of v0 = (37.3 m/s)i when its rockets fire, giving it an acceleration of a = (2.55 m/s2)i + (4.19 m/s2)k. How fast, in m/s, is the rocket moving 6.06 s after the rockets fire?
A boxer's fist and glove have a mass of m = 1.04 kg. The boxer's fist can obtain a speed of v = 9.25 m/s in a time of t = 0.21 s. Write a symbolic expression for the magnitude of the average acceleration, aave, of the boxer's fist, in terms of the variables provided. Find the magnitude of the average acceleration, aave, in meters per square second. Write an expression for the magnitude of the average net force, Fb, that the boxer must apply to his fist to achieve the given velocity. (Write the expression in terms of m, v and t.) What is the numerical value of Fb, in newtons?
A car is initially traveling at a rate of 65 feet per second. The acceleration of the car is 3 feet per second squared. Determine the displacement of the car at time t if the displacement at t=5 seconds is 29 feet. Do not include "s(t)=" in your answer.
The head injury criterion (HIC) is used to assess the likelihood of head injuries arising from various types of collisions; an HIC greater than about 1000 s is likely to result in severe injuries or even death. The criterion can be written as HIC = (aavg/g)2.5Δt, where aavg is the average acceleration during the time Δt that the head is being accelerated, and g is the free-fall acceleration. Shown is a simplified graph of the net force on a crash dummy’s 4.5 kg head as it hits the airbag during a automobile collision. What is the HIC in this collision?
A red train traveling at 72 miles/hour (mph) and a green train traveling at 100 mph are headed toward one another along a straight, level track.
