What is the instantaneous velocity at t = 2 of a particle moving along a line if s (t) = 3t - 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/5 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 & 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 s in time is given by 8 = 180t - 16t , for what value(s) of t in seconds is the particle moving to the left? O A. 0 5. 625 O D. O
