An object is initially moving at a rate of 14.5 m/s in the positive x-direction. What acceleration is required for the object to increase its speed to 26.6 m/s i over a distance of 14 m?

Page 5 of 8 5. As I drive on a back-country road, I suddenly see a deer "frozen" in the headlights. I was driving at 11.4 m/s, but immediately apply the brakes and slow with an acceleration of 3.80 ". a. If the deer was 20.0 m from my vehicle when the brakes were applied, how close did I come to hitting the deer? b. How much time was needed for my vehicle to stop?

Problem 4: A particle moving along a straight path has an acceleration defined by a = 0.6s + 3.6 ft/s², where s is in feet. If the particle's speed is 1.2 ft/s at s = 0, find its speed when s = 8 feet.

i attached the question.

Butch and Sundance are standing on the edge of a cliff, arguing about whether ornot they should jump into the water below. Butch drops a small rock and is able to count to 7-Mississippi (i.e., 7 seconds) before it hits the water. Assume g=10 m/s2.Ignore air resistance.a) If they were to jump, how fast would they be going just before they hit the water?(in m/s)b) How high is the cliff in meters?c) Transform the velocity in a) to mi/hr and the height in b) to feet. Would you jump?

The velocity and acceleration of an object at a certain instant are 3 = (3.0 m/s)j ä = (5 m/s²)î At this instant, the object is Ospeeding up and moving in a straight line. speeding up and following a curved path. slowing down and following a curved path. moving with constant speed and following a curved path. slowing down and moving in a straight line.

Chapter 02, Problem 086 A motorcyclist who is moving along an x axis directed toward the east has an acceleration given by a = (6.20 - 2.20t) m/s2 for 0 s t S 6.0 s. At t = 0, the velocity and position of the cyclist are 2.90 m/s and 7.3 m. (a) What is the maximum speed achieved by the cyclist? (b) What total distance does the cyclist travel between t = 0 and 6.0 s?

The acceleration of a body moving along the X-axis is a = (4x - 2) , where x is in m %3D meters. Given that Un 10 m/s at xo 0, what is its velocity when x = %3D 10 m? 25.7 m/s 29.3 m/s -29.3 m/s 21. 4 m/s O 23.2 m/s

The next few questions challenge you to figure out the acceleration due to gravity ( g ) on various hypothetical alien planets. On Planet #1, you drop a stone from rest, 92.3 m above the ground, and the stone hits the ground 6.18 s later. What is the value of g on Planet #1? 1 14.94 m/s^2 2 29.87 m/s^2 3 4.83 m/s^2 4 2.42 m/s^2

A rocket-powered sled moves along a track, eventually reaching a top speed of 150 m/s to the west. It then begins to slow down, reaching a complete stop after slowing down for 4.21 s. What was the sled s average acceleration and velocity during the slowdown phase? 35.6 m/s^2 east, not enough information 0 m/s^2 0, 75 m/s west 35.6 m/s^2 west, not enough information
