The position of a body moving along the s-axis is given by 3 = t3 12t2 + 36t. with .5 in meters and t in seconds. (a) Find the body's acceleration each time the velocity:r is zero. If there is more than one answer, enter a comma separated list. If there are no answers, enter NONE. Acceleration = C] [rt/52 (b) Find the body's velocity each time the acceleration is zero. If there is more than one answer, enter a comma separated list. If there are no answers, enter NONE. Velocity = C] m/s (c) Find the total distance traveled by the body from t = 0 to t = 4. Total distance = C] Ill If a ball is thrown vertically upward from the roof of a 48-foot high building with a velocity of 15 ftlsec, its height, in feet, after t seconds is .505) = 48 + 15:: 1519. a.) What is the maximum height, in feet, the ball reaches? Answer: C] b.] What is the velocity, in feet per second, of the ball when it hits the ground (height 0)? Answer: B
