The motion of the particle along a straight line is governed by the relation a = t3 – 2t² + 7 where a is the acceleration in m/s² and t is the time in seconds. At time t = A second, the velocity of the particle is v m/s and the displacement is d m. Calculate the displacement, velocity and acceleration at timet = 2 seconds. * 0.5 A = second V = .m/s d = 25

A fly walks with a speed of 1 cm/sec in every direction of a piece of paperwhich is considered to be xy plane. If the fly walks away from the origin inthe direction of u = i − 7j, the temperature it measures increases at a rateof 3◦C/sec. If the fly walks away from the origin in the direction v = i + j,the temperature it measures decreases at a rate of 2◦C/sec. Find how fast thetemperature changes if the fly moves away from the origin in the positive x axisdirection.

Your answer is partially correct. The displacement of a particle is given by s = 5t3 - 70t2 + 105t - 57 where s is in feet and t is in seconds. Plot the displacement, velocity, and acceleration as functions of time for the first 11 seconds of motion. After you have made the plots, answer the questions.

+51 suspension You are an engineer designing the suspension of an ATV. You want to ensure that the vehicle doesn't "bottom out" even when landing from being airborne. An approximation describing the vertical acceleration of the suspension upon impact is I a(s) 9.8(1 12s) m/s² where the initial velocity at impact is v=1.5 m/s with the spring initially uncompressed, s = 0 m A) What is the vertical velocity of the ATV chassis after the spring is compressed 0.1 m? B) What is the maximum distance the spring gets compressed? (This occurs when the ATV's vertical motion comes momentarily to rest)
