A car is moving along a straight test track. The position (in feet) of the car, s(t), at t (seconds)s(t) (feet) various times t is measured, with the results shown to the right. Use the table to answer 1 parts (a) through (d). 11 13 23 (a) Find the average velocity from 1 to 3 seconds. The average velocity is 5 ft/s. (Type an integer or a decimal.) (b) Find the average velocity from 3 to 5 seconds. The average velocity is 1 ft/s. (Type an integer or a decimal.) (c) Find the average velocity from 5 to 7 seconds. The average velocity is |fu/s. (Type an integer or a decimal.)If an object is dropped from a 182foothigh building, its position {in feet above the ground} is given by sit) = 1th + 182, where t is the time in seconds since it was dropped. {a} What is its velocity 1 second after being dropped? [b] When will it hit the ground\"? (Hint: Solve stt} = D.) {c} What is its velocity upon impact {at the instant when it hits the ground)? i The object's velocity 1 second after being dropped is D sec' {Simplify your answer.) Let f(x) = 2x + 3x and g(x) = - 4x - 1. Find fig(1) ]. fig(1)] =Let f(x) = 2x2 - 3x and g(x) = 3x - 1.
