The Skydiver Again When a skydiver jumps from an airplane, her downward velocity, n feet per second, before she opens her parachute is given by = 176 1 0.834t, where t is the number of seconds that have elapsed since she jumped from the airplane. We found earlier that the terminal velocity for the skydiver is 176 feet per second. How long does it take for her to reach 90 of terminal velocity?
Falling Ball Using calculus, it can be shown that if a ball is thrown upward with an initial velocity of 16 ft/s from the top of a building 128 ft high, then its height h above the ground t seconds later will be h=128+16t-16t2 During what time interval will the ball be at least 32 ft above the ground?
Alexanders Formula One interesting problem in the study of dinosaurs is to determine from their tracks how fast they ran. The scientist R. McNeil Alexander developed a formula giving the velocity of any running animal in terms of its stride length and the height of its hip above the ground. The stride length of dinosaur can be measured from successive prints of the same foot, and the hip height roughly the leg length can be estimated on the basis of the size of a footprint, so Alexanders formula gives a way of estimating from dinosaur tracks how fast the dinosaur was running. See Figure 2.45. If the velocity v is measured in meters per second, and the stride length s and hip height h are measured in meters, then Alexanders formula is v=0.78s1.67h1.17. For comparison, a length of 1 meter is 39.37inches, and a velocity of 1 meter per second is about 2.2milesperhour. First, we study animals with varying stride lengths, but all with a hip height of 2meters so h=2 i. Find the formula for the velocity v as a function of the stride length s. ii. Make a graph of v versus s. Include stride lengths from 2to10meters. iii. What happens to the velocity as the stride length increases? Explain your answer in practical terms. iv. Some dinosaur tracks show a stride length of 3meters, and a scientist estimates that the hip height of the dinosaur was 2meters. How fast was the dinosaur running?
