The y-coordinate of a particle in curvilinear motion is given by y = 7.5t3 -7.5t, where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by a, = 2.8t in./sec?. If the velocity of the particle in the x-direction is 5.3 in./sec when t = 0, calculate the magnitudes of the velocity v and acceleration a of the particle when t = 1.6 sec. Construct v and a in your solution. Answers: When t = 1.6 sec, V = in./sec i in./sec? a =

Your answer Question 2: A snowboarder starts from rest at the top of a double black 3 points diamond hill. As she rides down the slope, GPS coordinates are used to determine her displacement as a function of time given by the image below, where x and t are expressed in feet and seconds, respectively. Determine the displacement, average velocity, average speed and average acceleration for the time period from t=2 seconds to t=7 ft; v_avg = ft/s; seconds. Write your answer in the format (d = ft/s^2) * %3D V_sp = ft/s; a_av = x = 0.5t³ + t² + 2t Your answer

QUESTION 3 Night-time conditions prevail on a highway. A vehicle is driving at a speed of 87 mph when it notices an object located 1000 ft away. The vehicle Immediately hits the brake. Assuming a perception reaction time of 3.4 seconds (larger due to night time), calculate the distance moved by the vehicle between seeing the object and hitting the brakes. Report your answer correct to two decimal places in "feet" units. QUESTION 4 A driver with 20/15 vision can read a given sign at a distance of 24 ft from the sign. Calculate the maximum distance at which driver with 20/20 visual acuity will be able to see the same sign? (Report your answer to one digit after the decimal)
