1.) (d)

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 5 f/s. (Type an integer or a decimal.) (d) Estimate the instantaneous velocity at 5 seconds using the formula for estimating the instantaneous rate (with h =2). The instantaneous velocity is approximately |fu/s (Type an integer or a decimal.)If an object is dropped from a 182toothigh building, its position {in feet above the ground} is given by s{t] = 1lt2 + 182, where t is the time in seconds since it was dropped. {a} What is its velocity 1 second after being dropped? {bl When will it hit the ground\"? (Hint: Solve s(t} : D.) {c} What is its velocity upon impact {at the instant when it hits the ground)? it The object's velocity 1 second after being dropped is El sec' {Simplify your answer.)
