Textbook Question

Chapter 3, Problem 58PP

_BIO Ballistic seed dispersal. Some plants disperse their seeds by having the fruit split and contract, propelling the seeds through the air. The trajectory of these seeds can be determined by using a high-speed camera. In one type of plant, seeds are projected at 20 cm above ground level with initial speeds between 2.3 m/s and 4.6 m/s. The launch angle is measured from the horizontal, with +90° Corresponding to an initial velocity straight upward and −90° straight downward

58. The experiment is designed so that the seeds will move no farther than C.20 mm between photographic frames What minimum frame rate for the high-speed camera is needed to achieve this?

A. 250 frames/s
B. 2500 frames/s
C. 25,000 frames/s
D. 250,000 frames/s

3.63 • Leaping the River II. A physics professor did daredevil stunts in his spare time. His last stunt was an attempt to jump across a river on a motorcycle (Fig. P3.63). The takeoff ramp was inclined at 53.0°, the river was 40.0 m wide, and the far bank was 15.0 m lower than the top of the ramp. The river itself was 100 m below the ramp. Ignore air resistance. (a) What should his speed have been at the top of the ramp to have just made it to the edge of the far bank? (b) If his speed was only half the value found in part (a), where did he land? Figure P3.63 53.0° 100 m 40.0 m→ 15.0 m

Please solve and answer the question correctly please. Thank you!!

You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 5.00 s after it was thrown. What is the speed of the rock just before it reaches the water 25.0 m below the point where the rock left your hand? Ignore air resistance.
