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?

The speed of a bullet as it travels down the barrel of arifle toward the opening is given by v ! (- 5.00 x10*7)t*2+(3.00 x10*5)t, where v is in meters per second and t is inseconds. The acceleration of the bullet just as it leaves thebarrel is zero. (a) Determine the acceleration and positionof the bullet as a function of time when the bullet is in thebarrel. (b) Determine the length of time the bullet is accelerated. (c) Find the speed at which the bullet leaves thebarrel. (d) What is the length of the barrel?
Can you also help w C? C: Determine the direction of the velocity of the sandbag at a time 0.285 ss after its release. TIA
Playing jackstone as a kid, you discovered that there is a certain time before the rubber ball falls and you took advantage of this when picking up the stars on the floor. If you threw the ball (GIVEN A)m/s up into the air, how fast will it be moving at a height of (GIVEN B)cm? How much time has elapsed upon reaching this height?
In his novel From the Earth to the Moon (1865), JulesVerne describes a spaceship that is blasted out of a cannon, calledthe Columbiad, with a speed of 12,000 yards>s. The Columbiad is900 ft long, but part of it is packed with explosives, so the spaceship accelerates over a distance of only 700 ft. Estimate the acceleration experienced by the occupants of the spaceship duringlaunch. Give your answer in m>s2. (Verne realized that the “travelers would . . . encounter a violent recoil,” but he probably didn’tknow that people generally lose consciousness if they experienceaccelerations greater than about 7g ∙ 70 m>s2.)
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.
After a ball rolls off the edge of a horizontal table at time t = 0, its velocity as a function of time is given by:v = 1.2 i - 9.8t jwhere v is in meters per second and t is in seconds. The ball’s displacement away from the edge of the table, during the time interval of 0.380 s for which the ball is in flight, is given by:Δ⃗r=∫00.380s⃗vdtTo perform the integral, you can use the calculus theorem:∫[A+Bf(x)]dx=∫Adx+B∫f(x)dx You can think of the units and unit vectors as constants, represented by A and B. Perform the integration to calculate the displacement of the ball from the edge of the table at 0.380 s
An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water. He throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. The first stone has an initial speed of 2.06 m/s. (c) What is the speed of each stone at the instant the two stones hit the water?

You are on the roof of a Physics Building, 35 m above the ground. Your physics professor, who is 1.83 m tall, is approaching the building at constant speed of 1.75 m/s. If you wish to drop an egg on his head, how far should your professor be when you release the egg? Express your answer without rounding off PLEASE
You are talking with a cell phone while trailing a police car by 20m; both ypur car andthe police car traveling at 100km/h. Your conversation diverts your attention fromthe police car for 2,0 s. At the beginning g of that 2,0s the police officer beginsbraking suddenly at 6m/s2. A- What is the separation between the two cars whenyour attention finally returns? Suppose that you take another 0,3 s to realize yourdanger and begin braking. B- If you too brake at 6m/s2, what is your speed when youhit the police car.
The brakes on your car can slow you at a rate of 5.2 m/s2. (a) If you are going 137 km/h and suddenly see a state trooper, what is the minimum time in which you can get your car under the 90 km/h speed limit? (The answer reveals the futility of braking to keep your high speed from being detected with a radar or laser gun.) (b) Graph x versus t and v versus t for such a slowing.
