2.87 *** In the vertical jump, an athlete starts from a crouch and jumps upward as high as possible. Even the best athletes spend little more than 1.00 s in the air (their "hang time"). Treat the ath- lete as a particle and let ymax be his maximum height above the floor. To explain why he seems to hang in the air, calculate the ratio of the time he is above ymax/2 to the time it takes him to go from the floor to that height,. Ignore air resistance.

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 :(
Use a graphing utility to generate the trajectory of a paper airplane whose equations of motion for t ≥ 0 arex = t − 2 sin t, y = 3 − 2 cos t Assuming that the plane flies in a room in which the floor is at y = 0, explain why the plane will not crashinto the floor. [For simplicity, ignore the physical size of the plane by treating it as a particle.] How high must the ceiling be to ensure that the plane does not touch or crash into it?
A rocket ship has a position given by x(t)=bt2 meters. In order for it to reach a velocity of 5,000 m/s in 40,000 meters, what must be the value of b?
In 1865, Jules Verne proposed sending men to the Moon by firing a space capsule from a 220-m-long cannon with final speed of 10.97 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during their launch? (A human can stand an acceleration of 15g for a short time.) Compare your answer with thr free-fall acceleration, 9.80 m/s^2
An ant crawls on the surface of a ball of radius b in such a manner that the ant's motion is given in spherical coordinates by the equations r = b; phi = omega*t; theta = pi/2 * [1 + 1/4 * cos(400t)] Find the speed of the ant as a function of the time t. What sort of path is represented? by the above equations ?
Consider a dragster that, when the light turns green, accelerates uniformly from rest and completes a 372 meter race in a time of 6.61 seconds. a) During this period, what is the dragster's acceleration expressed as a multiple of the acceleration due to gravity, g? b) If the dragster could continue with this average acceleration, what would its speed be, in miles per hour, after it has traveled a total distance of 1.6km1.6km, which is approximately one mile?
An object's velocity as a function of time in one dimension is given by the expression; v(t) = 2.71t + 7.88 where are constants have proper SI Units. What is the object's velocity at t = 4.19 s?
Suppose (unrealistically) the velocity of the skydiver is 80 m/s, for 0 ≤ t ≤20,and then it changes instantaneously to 6 m/s, for 20 ≤ t ≤ 40. Sketchthe velocity function and, without integrating, find the distance theskydiver falls in 40 s
What is the velocity function, v(t), of a train accelerating at a rate of 50m/s^2 and traveling at a rate of 100m/s after t=36s?
A daredevil jumps off a tall building. He falls freely for several secondsbefore releasing his parachute. His height (h) in meters, ? seconds afterjumping can be modeled by h = −4.9?2 + ? + 360 before he releases hisparachute and h = −4? + 142 after he released his parachute. How longafter jump did he release his parachute?
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?
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?
