There is a 250-m-high cliff at Half Dome inYosemite National Park in California. Suppose aboulder breaks loose from the top of this cliff.(a) How fast will it be going when it strikes theground? (b) Assuming a reaction time of 0.300s, how long a time will a tourist at the bottomhave to get out of the way after hearing thesound of the rock breaking loose (neglecting theheight of the tourist, which would becomenegligible anyway if hit)? The speed of sound is335.0 m/s on this day.

Given, height of cliff is h = 250m the initial velocity of the boulder is ui=0 a) If vf is the…

You’re trying to find your classroom in the labyrinth that is Gilman Hall, walking through the halls at an average pace of 1.4 m/s.

You go to the roof of the twelve story building and look over the edge to the reflecting pool 170 feet below. You drop your book over the edge at the same instant that azmira chucks his book straight down at 48 feet per second . By how many seconds does his book into the water?
A runner with a good awareness of her pace runs along a path of unknown length at a speed of 0.1250.125 mi/min and then walks back to her starting point at a speed of 0.04500.0450 mi/min. She neglects to note her time for each part of her path but does measure the total round-trip time to be 50.050.0 min. How far did she run? (Do not include walking distance.)
Sophia is cruising at 28.0 m/s down Lake Avenue and through the forest preserve. She notices a deer jump into the road at a location 62.0 m in front of her. Ima first reacts to the event, then slams on her brakes and decelerates at -8.10 m/s2, and ultimately stops a picometer in front of the frozen deer. What is Ima's reaction time? (i.e., how long did it take Sophia to react to the event prior to decelerating?
To test your friend's reaction speed, you drop a meter stick form just above his hand, and he catches it after it has fallen 25.0 cm. What is his reaction time, according to this single measurement? Answer in seconds.

Wyle E. Coyote hears a constant “Beep! Beep!” from around the corner of a cliff. Thinking it might be the Road Runner, he scampers up to speed and runs towards the sound to the East. On coming around the corner, he sees that it is not the Road Runner, but a truck coming towards him towards the West. The speed of the truck is 25 m/s. The speed of the Coyote is 100 m/s. The Coyote hears a frequency of 5500 Hz. The temperature of the air is 300 K. The mass of the truck is 1500 kg. The mass of the Coyote is 90 kg. Assume the air is an ideal gas with γ = 1.40 and the air molecules have a mass of 4.8*10-26 kg. The Boltzmann constant is k = 1.38*10-23 J/K. a. What is the speed of sound in this air? b. What is the original frequency of the horn on the truck? c. Assuming a perfectly inelastic collision, what is the final speed and direction of the truck, Coyote conglomerate (ignore any friction with the road)?
A train starts from rest and accelerates uniformly, until it has traveled 5.6 km and acquired a velocity of 42 ms. The train then moves at a constant velocity of 42 m/s for 420 s. The train then slows down uniformly at 0.065 m/s2, until it is brought to a halt. The acceleration during the first 5.6 km of travel is closest to: O 0.20 m/s² O 0.14 m/s² O 0.19 m/s² 0.17 m/s² O 0.16 m/s²
The velocity of a particle traveling in a straight line is given by v = (6t – 3t²) m/s, where t is in seconds. If s = 0 when t = 0, determine the particle's deceleration and position when t = 5 s. How far has the particle traveled during the t = 5 s time interval, and what is its average speed? I need a clear answer by hand, not by keyboard | dybala
