Can you solve w/ steps and explanation? thanks.
Applying principles of dynamics (with step by step solutions pls i give 5 stars) The velocity of a particle which moves along the a linear reference axis is given by v = 2—4t— 6t3, t is in seconds while v is in meters per second. Eval-uate the position, velocity and acceleration when t = 3 seconds. Assume an your own initial position and initial point in time. Further, set a variable for position as you see fit.

Use integrals with limits to complete the following. Credit will not be given for integrals without limits. 1. A jet lands on a runway. Between the time the jet touches the ground (t = 0) and when it comes to rest, the jet has a velocity given by v(t) = 160.0 - 2.5 ³. m m . (a) Write down a definite integral that will give you the displacement of the jet between t = 1.0 s and t = 3.0 s. (b) Evaluate the definite integral you wrote out in part (a) to determine the displacement of the jet between t = 1.0 s and t = 3.0 s?
On a certain stretch of track, trains run at 60 mph. How far back of a stopped train should be a warning torpedo be placed to signal an oncoming train? Assume that the brakes are applied at once and retard the train at the uniform rate of 2 ft/second squared. Second assume that the operator will take 2.5 seconds to process the information before applying the breaks.
