2:20 AT&T NIGER A paratrooper is initially falling downward at a speed of 27.5 m/s before her parachute opens. When it opens, she experiences an upward instantaneous acceleration of 75.0 m/s2. Part If this acceleration remained constant, how much time would be required to reduce the paratrooper's speed to a safe 5.75 m/s? (Actually the acceleration is not constant in this case, but the equations of constant acceleration provide an easy estimate.) peringe 2:20 AT&T Part How far does the...

A paratrooper is initially falling downward at a speed of 27.9 m/s before her parachute opens. When it opens, she experiences an upward instantaneous acceleration of 73 m/s2. (a) If this acceleration remained constant, how much time would be required to reduce the paratrooper's speed to a safe 5.20 m/s? (Actually the acceleration is not constant in this case, but the equations of constant acceleration provide an easy estimate.) (b) How far does the paratrooper fall during this time interval?

A paratrooper is initially falling downward at a speed of 29.1 m/s before her parachute opens. When it opens, she experiences an upward instantaneous acceleration of 67 m/s2. (a) If this acceleration remained constant, how much time would be required to reduce the paratrooper's speed to a safe 5.50 m/s? (Actually the acceleration is not constant in this case, but the equations of constant acceleration provide an easy estimate.) (b) How far does the paratrooper fall during this time interval?

Please show all your work.
5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...

2. A car moves along anx-axis through a distance of 900 m, starting from rest (at r-0 m) and stopping at x-900 m. It accelerates at +6 m/s through first 10 s of time. Then, through the remaining part of that distance, it slows down with constant acceleration until it stops. What are the: (a) car's maximum speed? (b) distance traveled during the first 10 s of time? (c) acceleration through the remaining part of the distance? (d) time elapsed...

Tutorial Exercise Consider a 75.5-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.93 m/s in 0.525 s. It travels with this constant speed for the next 5.00 s. The elevator then undergoes a uniform acceleration in the negative y direction for 1.95 s and comes to rest. (a) What does the spring scale register before the...

Two Thrown Balls 1 2 3 45678 A blue ball is thrown upward with an initial speed of 19.8 m/s, from a height of 0.6 meters above the ground. 2.4 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 8.9 m/s from a height of 22.3 meters above the ground. The force of gravity due to the earth results in the bals each having a constant downward acceleration of 9.81 m/s2....
