Question

December 12, 2019 Instructor John Eustace 1.) A basketball refieres tesses the ball straight for the starting tip-off. Al what velocity basketball player leave the ground to rise 125 m above the floor in an attempt to get the Assume that the 1.25m is the top of the juma viax Ch.2 5 pts A) 5.0 m/s B) 8.2 m's C) 52 36 m's D) 13 m/s E) 10 m/s 2.) Dr. John Paul Stapp was US Air Force officer who studied the effects of extreme deceleration on the human body. On December 10. 1954. Stapp rode a rocket sled, acce from rest to a top speed of 282 m/s (1015 km/h) in 5.00 s, and was brought jarringly ba in only 1.40 s! Calculate his (a) acceleration and (b) deceleration. Express cach in mull (9.80 m/s2) by taking its ratio to the acceleration of gravity. Ch. 2 10 Pts A) 45.2m/s B) 53.8m/s C) 56.5m/s? D) 64.8m/s E) 56.4m/s 101.4m/s 4.6g 10.4g 101.8m/s? 5.5g 10.4g 301.5m/s? 5.8g 30.8g 201.4m/s6.66g 20.55g 201.4m/s? 5.76g 20.55g 3.) An object is dropped from a height of 75.0 m above ground level. (a) Determin traveled during the first second. (b) Determine the final velocity at which the obje ground. (c) Determine the distance traveled during the last second of motion befe ground. Ch 2 15 Pts A) 4.9m B) 4.9m C) 4.9m D) 5.3m E) 5.6m 32m/s - 31.3m 26m/s - 36.3m 38m/s - 34.3m 32m/s - 35.3m 26m/s - 33.3m

Answer 1

o ve = 20h a Vase x 10 x 1.25 v= Jas - S m/s.
