If you were to drop a rock from a tall building, assuming that it had not yet hit the ground, and neglecting air resistance, after 6.3 s; (acceleration due to gravity g = 10 m/s²) a) At what speed would it be traveling (in m/s)? Submit Answer Tries 0/2 b) how far of a distance would it have fallen (in m)?

(b) Suppose instead that the true speed of the car as a function of time is described by v(t) = 30√/t (still from t = 0 to t = 4). Sketch a graph of the car's speed vs. time. (c) Since the speed is no longer constant, it is much harder to calculate the distance traveled. But we can still try. Suppose we wanted to calculate how far the car went in the sin minute from 1:00 and 1:01. i. Let's pretend that the car's speed is constant for this single minute. What might be a reasonable approximation for the car's speed, in this scenario? (There is no one single correct answer to this question; make your best estimate.) ii. Under this assumption, approximately how far did the car go during this minute? (Hint: Don't forget that a minute is hours.) 60

From the bottom of a 25m well, a stone is thrown vertically upward with an initial velocity 30m/s. (a) How far is the ball out of the well?(b) The stone before returning into the well, how many seconds was outside of the well?

A motorist traveling with a constant velocity of 30 m/s passes E school-crossing comer, where the speed limit is 20 km/h. Just as the motorist passes, a traffic officer on a motorcycle stopped at the comer starts off in pursuit with a constant acceleration of 2.0 m/s What is the officer's speed at that point (in m/s) (when the officer catches up with the motorist)? Attanpt 1 Hour, 59

9) Generic Villain, in an airplane, is chasing Generic Hero who is driving a car. The speed of the airplane is 147 m/s and the speed of the car is 51.0 m/s. If the Villain, at an altitude of 1.00E2 m, wants to drop a bomb on the Hero (and assuming the airplane is in level flight) how far should they be away from the car when they do so? (If you care, the hero gets away with some generic special effects and, you know, turning...) (434 m)

A ball is dropped from the top of the cliff 25.0-meter high. (a) How long will it take for the ball to reach the foot of the cliff? (b) What is the velocity of the ball upon reaching the foot of the cliff?

i need the answer quickly

make answer clear

i cant figure out these two parts

Question .1 A stone is thrown vertically upward with a speed of 24.0 m_s. (a) How fast is it moving when it is at a height of 13.0 m? (b) How much time is required to reach this height? (c) Why are there two answers to (b)?
