You run and jump off a short cliff into a lake. If you jump with a velocity of 4 m/'s at 150, and the cliff is 6 m tall a.) How long does it take to hit the water? b.) How far from the cliff are you when you land?
Chapter 5, Section 5.4, Question 042 If you jump out of an airplane and your parachute fails to open, your downward velocity (in meters per second) t seconds after the jump is approximated by v (t) = 49 ( İ-(0.8187)' ) . (a) Write an expression for the distance you fall in T seconds (b) If you jump from 4400 meters above the ground, estimate, using trial and error, how many seconds you fall before hitting the ground. Round your...
You test your vertical leap and find that you can jump to a height 0.51 m above the ground. a) What velocity do you need to have when you leave the ground to go that high? b) How much hang time will you have? (How long are you off the ground?)
You sign up for a bungee jump off a tall bridge. A thick rope with a fixed length of 16.0 m is tied to the bridge, and a bungee cord with an unstretched length of 8.00 m is then connected to the rope. The other end of the bungee cord is attached to your legs. You step off the bridge, falling from rest. The bungee cord does not start exerting any force on you until you have fallen a distance...
Potpourri A fire hose held near the ground shoots water at a speed of 8.5 m/s. At what two angles should the nozzle point so that the water lands 3.1 m away? Extreme sports enthusiasts have been known to jump off the top of the Rachel Carson Bridge, a bridge of height 23 m in Pittsburgh. Assume a jumper runs horizontally off the top of the bridge deck with a speed of 3.0 m/s and enjoys a free fall until...
Homework 9 Name Hour 1.) A cat stretches and knocks a pen horizontally off a 1.1 m tall desk. If the pen ands 35 cm from the edge of the desk: a.) How long does it take the pen to hit the ground? b.) What horizontal velocity does the cat push the pen with? s and ently tacce the p 2.) You run and jump off a short cliff into a lake. If you jump with a velocity of 4...
You need junk food and FAST! You jump off your scooter at a your favorite place, but with a history of a line. Usually you can expect to wait 375 seconds from the time you arrive until the personal finally takes your order (there is only one order taker). Service time averages 40 seconds. SHOW ALL WORK! Remembering ρ=λ/μ, L=λW, W=1/(μ-λ), Lq=ρL, Wq=ρW, Pn=(1-ρ) ρ^n What is the utilization of the server? _____% (1.0 pt) What is the expected time...
If you dropped a rock from a height of 1.1 m on 243 Ida, how long would it take to reach the ground? Express your answer to two significant figures and include the appropriate units. If you can jump 62 cm straight up on earth, how high could you jump on 243 Ida? (Assume the asteroid's gravity doesn't weaken significantly over the distance of your jump.) Express your answer to two significant figures and include the appropriate units. The asteroid...
1. Some raindrops fall from a height of l km. How fast would you expect them to be moving when they hit the ground? How fast is this in miles per hour? Does this agree with your experience? In the same spirit, the geatest height for a free jump into an airbag occurred by studntman Dan Koko in 1948. He fell 99.4 m, and hit an airbag while travelling at the speed of 88 mph. How fast would you have...
During a blackout, you are trapped in a tall building. You want to call rescuers on your cell phone, but you can't remember which floor you're on. You pry open the doors to the elevator shaft, drop your keys down the shaft, and hear them hit bottom at ground level 3.27 s later. Assume that the height of one floor is 3.0 m. 1.Making a simple calculation and remembering that the ground floor is numbered floor 1, you determine which...
