A stone is thrown with a velocity of 30m/s pointed 36.87 degrees above the horizontal from thetop of a cliff, 68.4m high.a. How far from the face of the cliff will it strike a horizontal plane through the base of thecliff?b. If sound travels approximately 350 m/s, how long after the stone is thrown will thesound of the impact be heard?12. The Y coordinates of a particle which moves along a curve are given by y = 20t + where y isin meters and t is in seconds. When t=2s, the total acceleration is 5m/s^2. If the component ofacceleration in the positive x-direction is constant and the particles starts from the origin withVx=0 at t=0, determine the total velocity and position of the particle when t=5s13. A rifle is fired from the top of a 90m building. The initial velocity of the bullet is 350 m/s and therifle is pointed 30 degrees above the horizontal.a. When will the bullet strike the ground?b. Where will the bullet strike the ground?c. What is the maximum height attained by the bullet?14. A particle travels counterclockwise around a circle of 36m radius so that the distance from afixed point O on the right end of a horizontal diameter is given by s = 20t + 2t where s is inmeters and t is in seconds. Determine:a. Acceleration x-axisb. Acceleration y-axis15. The driver of a car applies the brakes to produce a uniform deceleration. The speed is 90kph atthe bottom A and 54 kph at the top C, which is 80m along the road from A. The passengerexperiences a total acceleration of 3.2 m/s^2 at C and the radius of curvature at A is 255m.Neglecting the dimensions of the car, as compared with those of the path, determine the40m40B.a. The radius of curvature at Cb. The total acceleration at Ac. The acceleration at the inflection point B
