In World War II, there were several reported cases ofairmen who jumped from their flaming airplanes with noparachute to escape certain death. Some fell about 20,000feet (6000 m), and some of them survived, with few lifethreatening injuries. For these lucky pilots, the tree branchesand snow drifts on the ground allowed their deceleration to berelatively small. If we assume that a pilot’s speed upon impactwas 123 mph (54 m/s), then what was his deceleration?Assume that the trees and snow stopped him over a distanceof 3.0 m.
If it takes a bicyclist 20 seconds to reach a speed of10 mph from rest, what is her acceleration? For thenext 10 minutes, she moves at the constant speed of10 mph, and at this time, she applies her brakes, andthe bicycle decelerates to a full stop in 4 seconds. Whatis the total distance traveled by the bicyclist? Determine the average speed of the cyclist during the first20 seconds, 620 seconds, and 624 seconds.
A runner is moving with a speed of 2.68[m/s]. How long will it take the runner to complete a 5.0[km] race? Express your answer in seconds. Ignore the time it takes to reach this speed, and assume the runner is always at this speed.
My pug/bulldog mix, Georgia, who is blind and deaf, gets a whiff of her dinner. As soon as it registers to her that it's dinnertime, she runs 4.12 meters from the middle of our living room to our kitchen, where she is satiated with her grub. If it takes her 4.45 s to get to the kitchen, what was her speed in m/s to the nearest hundredth?
A model plane flew 100 m in 25.0 s followed by another 240 m in an additional 60.0 s, whereupon it crashed into the ground. How far did it’s travel in total? How long was it in the air? What was its average speed?
Starting from rest, a particle first accelerates at acceleration a through a distance d, then it continuesat constant speed for time t, and finally decelerates at a/4 before coming to rest. If the total distancetraversed is 20d, then d can be written as d = φt^2 , what is φ?
A car is travelling at a constant speed of 100 km.hr at NLEX when the driver noticed that the bridge 10 m away is cut off. If the driver immediately applied the brakes upon noticing the cut off bridge, what must be his deceleration so he would not fall to the river?
Suppose a car is traveling at +19.9 m/s, and the driver sees a traffic light turn red. After 0.269 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 5.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?
The velocity of a train changes from 0 to 60km/hr in 20 seconds. Assuming that it is uniformly accelerated, what is the acceleration in m/s2?
what is the average speed in m/s for a person who ran a mile in 4.04 minutes?
In a 100-rn race, the winner is timed at 11.2 s. The second-place finisher’s time Is 11.6 s. How far Is the second-place finisher behind the winner when she crosses the finish line? Assume the velocity of each runner is constant throughout the race.
A top fuel dragster can cover a quarter-mile (402 m) in 4.44 seconds, from rest. Assuming that the acceleration is constant, what acceleration will the driver experience? How many times greater is this than the acceleration of gravity?
