If the particle has y-components y = 0 and vy = 3.1 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 5.9 sec. Sketch the path for the first 5.9 seconds of motion, and show the velocity and acceleration vectors for t = 5.9 sec. Answers: V = ft/sec a = i ft/sec²arrow_forwardThe y-coordinate of a particle in curvilinear motion is given by y = 5.2t³ -2.6t, where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by ax = 3.8t in./sec². If the velocity of the particle in the x-direction is 12.2 in./sec when't = 0, calculate the magnitudes of the velocity v and acceleration a of the particle when t = 3.8 sec. Construct v and a in your solution. Answers: When t = 3.8 sec, V = a= MI MI in./sec in./sec²arrow_forward
