A snowboarder’s velocity is tracked by a pulse-laser velocimeter as she descends the slope. These velocity data are stored and analyzed via an embedded curve fitting procedure to determine a velocity function of v(t) = 1.5t2 + 2t + 2 (t is time in seconds and v is velocity in ft/s). At time equal 0, position (x) is zero. Find her position (e.g., distance traveled), velocity and acceleration formulations and values of each when time equals 15 seconds. Clearly write the formulas before finding respective values at t = 15 seconds!
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
