A bullet in a gun is accelerated from rest from the firing chamber to the end of the barrel at an average rate of 6.25 × 105 m/s2 for 8.3 × 10-4 s. What is the gun’s muzzle velocity (that is, the bullet’s final speed), in meters per second?
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?
You're an investigator for the National Transportation Safety Board, examining a subway accident in which a train going at 90 km/hkm/h collided with a slower train traveling in the same direction at 24 km/hkm/h . Your job is to determine the relative speed of the collision, to help establish new crash standards. The faster train's "black box" shows that it began negatively accelerating at 2.1 m/s2m/s2 when it was 52 mm from the slower train, while the slower train continued at constant speed. What do you report ?
A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?

A hard rubber ball, released at chest height, falls to the pavement and bounces back to nearly the same height. When it is in contact with the pavement, the lower side of the ball is temporarily flattened. Suppose the maximum depth of the dent is on the order of 1 cm. Find the order of magnitude of the maximum acceleration of the ball while it is in contact with the pavement. State your assumptions, the quantities you estimate, and the values you estimate for them.
A tennis ball with a speed of 13m/s is moving perpendicular to a wall. After striking the wall,the ball rebounds in the opposite direction with the speed of 7.839m/s. If the ball is in contact with the wall foe 0.0113s,what is the average acceleration of the ball while it is in contact with the wall? Take toward the wall to be the positive direction. Answer in units of m/s*2
Dr. John Paul Stapp was a U.S. Air Force officer who studied the effects of extreme acceleration on the human body. On December 10, 1954, Stapp rode a rocket sled, accelerating from rest to a top speed of 282 m/s (1015 km/h) in 5.00 s and was brought jarringly back to rest in only 1.40 s. Calculate his (a) acceleration in his direction of motion and (b) acceleration opposite to his direction of motion. Express each in multiples of g (9.80 m/s2) by taking its ratio to the acceleration of gravity.
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?
A European sports car dealer claims that his car will accelerate at a cnstant rate from rest to 100 km/h in 8 seconds. You test this by driving a car up to a straight, flat section of track that is 200m long and note that the speedometer increased by 20 m/s as you drove through it. Under what conditions would the dealer be correct?
The speed of a bullet as it travels down the barrel of arifle toward the opening is given by v ! (- 5.00 x10*7)t*2+(3.00 x10*5)t, where v is in meters per second and t is inseconds. The acceleration of the bullet just as it leaves thebarrel is zero. (a) Determine the acceleration and positionof the bullet as a function of time when the bullet is in thebarrel. (b) Determine the length of time the bullet is accelerated. (c) Find the speed at which the bullet leaves thebarrel. (d) What is the length of the barrel?
A rocket sled having an initial speed of 150 mi/hr is slowed by a channel of water. Assume that during the braking process, the acceleration a is given by a(v)=-mu v2 , where v is the velocity and mu is a constant. If it requires a distance of 2000 ft to slow the sled to 15 mi/hr, determine the value of mu?
