How far will a vehicle travel before coming to a stop if you have a reaction time of 0.10 seconds, a speed of 30.0 m/s, and can safely decelerate at 4.00 m/s^2. How long did It take the vehicle to stop?
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.
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?
If it usually takes you three hours to arrive to Aqaba (from Amman) using a passenger car with amax. Speed of 100km/hr, estimate the time you need to reach to the same point if you own thisvehicle
Bacteria move back and f01th by using their flagella (Structures that look like little tails). Speeds of up to 50m/s(50106m/s) have been observed. The total distance traveled by a bacterium is large for its size, while its displacement is small. Why is this?
A car going initially 60 mi/hr hits the brakes and skids to a stop in 4 seconds. What isthe acceleration in mi/hr/sec? What is the total distance covered by the car during itsdeceleration?
Driving along a crowded freeway, you notice that it takes atime t to go from one mile marker to the next. When you increaseyour speed by 7.9 mi>h, the time to go one mile decreases by 13 s.What was your original speed?
Jane is driving down the road at 20.0 m/s looking for a house address. when she sees the house, she slams on her brakes. If her reaction time is 1.20s and her car deaccelerates at 3.50 m/s^2, how far past the point where she first saw the house did her car come to rest? I feel like I need to use one of the 4 kinematics equations, but none seem to be giving me the correct answer when I plug in my numbers :(
assuming a chevy cruze may be operated indefinitely at 30 m/s with no stops for provisions and may be refueled in transit, how long (in years) would be required for the Chevy vehicle to travel one lightyear?
How far can a cyclist travel in 1.5 hours (h) if his average speed is 12 km/h?
A motorcycle patrolman starts from rest at a gasoline station 2 seconds after a cartravelling at a constant rate of 120 kph passes the gasoline station. If the patrolmanaccelerated at the rate of 6 m/s^2 until he reaches his max permissible speed of 150kph which he maintains. How long did it take the patrolman to overtake the car fromthe time he starts from the gasoline station?
What is the speed of a car going v=1.000mphv=1.000mph in SI units?
