An object is dropped (initial velocity is zero) from a height of 40 meters. Assume the acceleration due to gravity a=g=9.81 m/s^2. Calculate: a.) the object's final velocity just before it hits the ground b.) the time it took the object to hit the ground

A particle at rest undergoes an acceleration of 2.1 m/s2 to the right and 3.9 m/s2 up. a)What is its speed after 5 s in m/s? b)What is its direction with respect to the horizontal at this time? Answer between −180◦ and +180◦.

A ball is dropped from a height of 3 m and rebounds from the floor to a height of 2 m.a) What is the velocity of the ball just as it reaches the floor?b) What is the velocity just as it leaves the floor?c) If it is in contact with the floor for 0.02 s, what are the magnitude and direction of its average acceleration during the interval?

6. A stunt man drives a car at a speed of 20 m/sec off a ramp that is 30 m above the ground. The ramp leading up to the take-off point is inclined at 20°. a) What is the time for the upward part of the motion only? b) What is the maximum height of the car relative to the ground? c) How far from the base of the cliff does the car land?

Q1) The position of a particle traveling along a straight line is s(t) = (t²-3t²+C) ft, where tis in seconds and C is a constant. If s = 4 ft when t= 0, determine the velocity of the particle when t =4 s. What is the total distance traveled during the time interval t = 0 to t = 4 s? Also, what is the acceleration when t = 2 s?

Captain Marvel jumps straight up in the air with a velocity of 30m/s straight up. She reaches a maximum height and then falls back down due to gravity to the same level. This is not a projectile question. a) what max height will she reach? b) How long will it take her to return to the same height from which she jumped c) What will her velocity be when she is just about to hit the ground at the same level she jumped from
