Dr. John Paul Stapp was a U.S. Air Force officer who studied the effects of extreme acceleration on the human body. On December 10, 1954, Stapp rode a rocket sled, accelerating from rest to a top speed or 282 m/s (1015 km/h) in 4.3 s and was brought jarringly back to rest in only 1.3 s. Calculate his (a) magnitude of acceleration in his direction of motion and (b) magnitude of acceleration opposite to his direction of motion. Express each in multiples of g (9.80 m/s²) by taking its ratio to the acceleration of gravity. a. b.

One of my questions got solved and helped me so much thank you! Here’s another one please. Two trains are 9.82km apart. They travel in opposite directions, to each other. Train A has a speed of 5.87 km/h at departure and an acceleration of 0.29m/s squared. Train B has a speed of 20.3m/s at the start and an acceleration of 0.69m/s squared. B. Determine when the trains meet.
Dr. John Paul Stapp was a U.S. Air Force officer who studied the effects of extreme deceleration on the human body. On December 10, 1954, Stapp rode a rocket sled, accelerating from rest to a top speed of 282 m/s (1015 km/h) in 5.00 s, and was brought jarringly back to rest in only 1.40 s!Calculate the magnitude of his average acceleration during the first part of his motion. Express your answer in multiples of g by taking its ratio to 9.80 m/s2. calculate the magnitude his average deceleration during the second part of his motion. Express your answer in multiples of g by taking its ratio to 9.80 m/s2.
An object's position in the as a function of time obeys the equation; x(t) = 14.2/t2.17 + 5.1t3 where all constants have proper SI Units. What is the speed of the object in the x direction at t = 1.93 seconds?
To help travelers get around the airport, a shuttle was built between two terminals. Starting from rest, the shuttle accelerates at 0.447 m/s2 for 37.1 s, cruises at this constent velocity for 62.5 s, and then deaccelerates at -0.275 m/s2 until it comes to a stop. What is the distance between the terminals?
Please answer the following question(s): 1. The speed of a boat in still water is vá. A river flows with a speed of v₁. The boat travels distance of 19 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the vand v₁. Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "v" and "v": Do v" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. vb vb Downstream positive Vr Upstream negative Vr
Your answer is partially correct. An object falls a distance h from rest. If it travels 0.550h in the last 1.00 s, find (a) the time and (b) the height of its fall. (a) Number i 3.414 Units (b) Number i 58.140 Units m

"A jet plane is cruising at 320 m/sm/s when suddenly the pilot turns the engines up to full throttle. After traveling 4.8 km , the jet is moving with a speed of 400 m/sm/s. What is the jet's acceleration, assuming it to be a constant acceleration? Express your answer to two significant figures and include the appropriate units." I am having issues setting up word problems to begin solving. Need an easier method or technique to help deciper these.
An object is moving with an initial velocity of 5.8 i m/s and a final velocity 13.8 i m/s. The time taken for acceleration is 2.2 seconds. Calculate the acceleration in m/s2 to 2 sf. In your answer, you do not enter the i unit vector, but you do need to enter negative signs, if appropriate. e.g. if your answer is a = -5.4 i m/s,2 you would enter -5.4
