What is the displacement after 3 seconds of a particle moving along a line if s (t) = t3 + 2:2, where s is distance in feet, and t is time in seconds? O A. 15 ft. O B. 24 ft. 0 C. 31ft. O D. 33 ft. O E. 45 ft. What is the instantaneous velocity at t = 2 of a particle moving along a line if s (t) = 3t2 - 2t + 5, where s is in meters, and t is in seconds? O A. 6 m/s O B. 8 m/s O C. 10 m/s O D. 13 m/s O E. 14 m/sA pumpkin is thrown straight down from the top of a 250-foot building with an initial velocity of -14 feet per second. Its position s at time t is described by the function s (t) = -16t - 14t + 250 where's is in feet. What is the pumpkin's speed at time t = 3 seconds? O A. -110 feet per second O B. -82 feet per second O C. 64 feet per second O D. 82 feet per second O E. 110 feet per secondA particle starts from rest and is moving to the right along a horizontal line. If its position 5 in time is given by s = 180: 16:2. for what valuels] of t in seconds is the particle moving to the left? 0 A. 0955.625 0 e. t=5.625 O o.:>5.525 o [109511.25 O E. t> 11.25
