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? Figure P3.42
Why is the following situation possible? Emily challenges her friend David to catch a $1 bill as follows. She holds the bill vertically as shown in figure P2.29 with the center of the bill between but not touching David's index finger and thumb. Without warning, Emily releases the bill. David catches the bill without moving his hands downwards. David reaction time is equal to the average human reaction time. Avg human reaction time is .2s. Dollar bill is approx 15.5cm in length. I need help explaining this. Thank you.
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.
Two cars travel at the same time from two point (A and B), which are 10km apart. It took the first car 20 minutes to travel from point A to B while it took 16 minutes for the other car to travel from point B to A. After how many minutes did the cars passed by each other if they travel at their respective uniform velocities. Select one: a. 9.67 minutes b. 8.89 minutes c. 9.89 minutes d. 10 minutes
Two cars of the same speed of 4 m/s2 approach each other on parallel tracks. If the cars were initially at rest and 100 m apart, then they will be abreast (side by side) in ________________________. A. 5 s B. 10 s C. 20 s D. 40 s
A 50g superball traveling at 25m=s bounces o a brick wall and rebounds at 22m=s. A high-speed camerarecords this event. If the ball is in contact with the wall for 3:5ms, what is the magnitude of the averageacceleration of the ball during this time interval? (Note: 1ms = 1 x 10^-3 s)
You are driving a car along a straight road at 122 kph. Suddenly, you saw a cat crossing the road and you apply the brakes decelerating the car at a constant rate of -44 m/s^2. If your reaction time is 1.50 seconds, what is the shortest stopping distance from the moment you see the cat? Illustrate the problem.
A person drops a ball of 100g at rest from a height of 1000m. He observes that there is air resistance (in newtons) acting on the body and it is proportional to the velocity v (in meters per second). He also notes that the limiting velocity is 245 meters per second. a) What is the velocity and distance after t seconds?b) What is the time t at which the velocity will be one-fifth of the limitingvelocity?
Using the velocities determine where the 2 cars will collide when place 2.1m apart? Car A = 27.41 cm/s Car B = 29.57 cm/s
You step onto a hot beach with your bare feet. A nerve impulse, generated in your foot, travels through your nervous system at an average speed of 110 m/s. How much time does it take for the impulse, which travels a distance of 1.8 m, to reach your brain?
A simple way of measuring a person's reaction time is to let the person catch a freely-falling ruler or meter stick and then measure the distance from the point where the fingers of the person was placed before the ruler is released to the point where the person's finger was located after the ruler was released. If the distance of fall is 19 cm, what is the person's reaction time? A. 19 s B. 1.9 s C. 0.2 s D. 0.1 s
If the ball could continue to travel below it’s original level (through an appropriately shaped hole in the ground), then negative values of y corresponding to times greater than 6.04s would be possible. Compare the balls position and velocity 8.00s after the start of its flight. (Answers c =178m. Y= 76.8m, Vx= 22.2m/s, Vy= -48.8m/s Both images have background information to help solve the practice problem. (The correct answer is also provided) just need help with working it out.
