Speedometer readings for a vehicle (in motion) at 12-second intervals are given in the table. t (sec) v (ft/s) distance traveled ~ 0 12 24 36 48 60 Estimate the distance traveled by the vehicle during this 60-second period using the velocities at the beginning of the time intervals. distance traveled feet 40 29 36 40 34 30 Give another estimate using the velocities at the end of the time periods. feet

The equation for the motion of an object with constant acceleration is d= do + vt + at, where d is distance from a given point in meters, do is the initial distance from the starting point in meters, v is the starting velocity in meters per second, a is acceleration in meters per second squared, and t is time in seconds. A car is stopped at a traffic light. When the light turns green, the driver begins to drive, accelerating at a constant rate of 4 meters squared. A bus is traveling at a speed of 15 meters per second in another lane. The bus is 7 meters behind the car as it begins to accelerate. per second Find when the bus passes the car, when the car passes the bus, and how far each has traveled each time they pass one another. it lad wod

The velocity - time graph of the journey of a person is shown in the attached graph. How much distance, in meters, did the person cover during the whole journey, from time = 0 to time = 50 seconds? Round your answer to the nearest integer. Speed (m/s) 25 20 15 10 5 0 0 10 20 Time (s) 30 40 50

We first need to convert the period from days to seconds. (Pdays)(Ns/day) Ps Ps S = = S

A boulder starting from rest rolls down a hill in a straight line, which we shall call the xx axis. A graph of its position xx as a function of time tt is shown in the figure. (Figure attached)   1) Find the distance the boulder rolled between the end of the first second and the end of the third second. Express your answer in meters to one significant figure.   2) Find the boulder’s average speed during the first second. Express your answer in meters per second to one significant figure.   3) Find the boulder’s average speed during the second second. Express your answer in meters per second to one significant figure.   4) Find the boulder’s average speed during the third second. Express your answer in meters per second to one significant figure.   5) Find the boulder’s average speed during the fourth second. Express your answer in meters per second to one significant figure.   6) Find the boulder’s average speed during the first 4 seconds. Express your answer in meters per…
