The displacement of a particle is given by s = 5t3 - 70t2 + 105t - 57 where s is in feet and tis 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. Questions: Att = 2.9 i ft, v = i ft/sec, a = i ft/sec sec, Att = 6.5 ft, v = ft/sec, a = ft/sec sec, Att=7.8 ft, v = i ft/sec,a = ft/sec sec, The velocity is zero when t = sec and when t = sec

The velocity of a particle traveling in a straight line is given by v= (6t – 3t2) m/s, where t is in seconds. Suppose that s = 0 when t = 0. Part C How far has the particle traveled during the 3.7-s time interval? Express your answer to three significant figures and include the appropriate units.

1. For this series of 3 questions, a jet bike is moving along a straight road with the speed described by the v-s function v(s) = 2. s2/3, (v in [m/s] and sin [m]). Your final goal is to determine the velocity (v) at a specified time. But before that, you need to answer some other questions. 3) determine the velocity (v) when the time t = 7.1 s. Your answer must include 2 places after the decimal point, and the proper unit. Your Answer: Answer units

(1-C.s) m/s² where Cis a constant and sis Q13. The acceleration of a particle traveling along a straight line is a the position in m. If the constant Cis 0.1, the initial velocity vo is 0, and the initial position so = 1.7 m at time t = 0, determine the particle's velocity v when its position s = 4.8 m. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. Answer: =
