3. At a construction site a pipe wrench struck the ground with a speed of 24 m/s. a) From what height was it inadvertently dropped? b). How long was it falling? Problems
4. A key falls from a bridge that is 45 m above the water. It falls directly into a model boat, moving with constant velocity that is 12 m from the point of impact when the key is released. What is the speed of the boat?

1. How far does an automobile move while its speed increases uniformly from 15 kph to 45 kph in 20 seconds? 2. Cars A and B are traveling in the same direction at the same speed of 70 km/hr in a level road. Car A is 150 m ahead of car B. Car A decelerates at a constant rate of 2 m/s 2 . From this instant up to the time B overtakes A , how far has B traveled ? 3. An car starting from rest speeds up to 40 ft/s with a constant acceleration of 4 ft/s 2, runs at this speed for a time and finally comes to rest with a deceleration of 5 ft/s 2 . If the total distance traveled is 1000 ft, find the total time required. Problems (Seatwork)
4. A stone is thrown vertically upward an returns to earth in 10 seconds. How high did it go and what is its initial velocity? 5. A ball is thrown vertically upward with an initial velocity of 3m/s from a window of a tall building. The ball strikes the ground 4 seconds later. Determine the height of the window above the ground. Problems (Seatwork)
Acceleration as Function of Time and Velocity Sample Problem 1 A Ford Mustang moves in a straight line such that for a short time its velocity is defined by v = (3t 2 + 2t) ft/s, where t is in seconds. Determine its position and acceleration when t = 3 s. When t = 0, s = 0 .
Acceleration as Function of Time and Velocity Sample Problem 2 A particle moving along a straight line is subjected to a deceleration a = ( -2v 3 ) m/s 2 , where v is in m/s. If it has a velocity v = 8 m/s and a position s = 10 m when t = 0, determine its velocity and position when t = 4 s.

Seatwork 2. A particle travels along a straight line with a velocity v = (12 3t 2 ) m/s, where t is in seconds. When (t = 1 s, the particle is located 10 m to the left of the origin. Determine the acceleration when t = 4 s, the displacement from t = 0 to t = 10 s, and the distance the particle travels during this time period.
