A jet plane lands with a speed of 145 m/s and can accelerate at a maximum rate of -7.00 m/?2 as it comes to rest. a. From the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest? b. Can this plane land on a small tropical island airport where the runway is 0.9 km long? Why?

NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec.                                           Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.

Page < c. The acceleration is +1.5 m/s². d. The acceleration is +3.0 m/s². e. The acceleration cannot be determined. 2 Multiple Choice Questions 1. A car enters a 25-m intersection travelling with a velocity 5 m/s in the west direction. When it clears the intersection (after it covers the 25-m), it is travelling with a velocity of 10 m/s still in the west direction. What is the acceleration of the car? Assume that east is in the positive x-axis and west is in the negative x-axis. a. The acceleration is -9.81 m/s. b. The acceleration is -1.5 m/s².

A student fires a cannonball vertically upwards with a speed of 31.0m/s. Determine all unknowns and answer the following questions. Neglect drag and the initial height and horizontal motion of the cannonball. What was the cannonball's maximum height? unit How long did the cannonball rise? unit What was the cannonball's total flight time? unit

A dolphin in an aquatic show jumps straight up out of the water at a velocity of 15 m/s.   A: How long is the dolphin in the air in seconds? Neglect any effects due to his size or orientation.

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?

At a moment when a rocket is 1120 m above the ground, it is traveling straight upward with a speed of 955 m/s. At this instant a small piece detaches from the rocket and begins freefall travel. 1. a) Find the velocity of the piece the instant before it hits the ground. b) Find the time required for it to reach the ground.

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
