A car accelerates from rest to a certain velocity in a certain time. Assume that there is no friction, and that the engine power is constant. Consider the following scenarios independently.(a)How long would it take to reach the same velocity if the engine had half the power?a. Half the time. b. Same time. c. Double the time. d. Four times the time.(b)How long would it take to reach double the velocity (also from rest)?a. Half the time. b. Same time. c. Double the time. d. Four times the time.(c)The car has a mass of 1130 kg and can accelerate from rest to 27 m/s in 6 seconds. Assuming no friction, what constant engine power would accomplish this?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
