A graph of position versus time for a certain particle moving along the x-axis is shown in the figure below. Find the average velocity in the following time intervals. x (m) 10 6 0 1 3 4567 t (s) -6 (a) 0 to 2.00s Enter a number differs from the correct answer by more than 10%. Double check your calculations. m/s (b) 0 to 4.00 s Your response differs from the correct answer by more than 100%, m/s (c) 2.00 s to 4.00 s The response you submitted has the wrong sign. m/:s (d) 4.00 s to 7.00s The response you submitted has the wrong sign. m/s (e) 0 to 8.00 s Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s

Given v(t) = 21 + 20 t, where v is in m/s and t is in s, use calculus to determine the total displacement from t₁ = 1.5 s to t₂ = 3.1 s. Express your answer using two significant figures.

Problem 3: You throw an object up with a speed of voy = 7 m/s from a height of y = 25 m. %3D Part (a) How long, in seconds, does it take for the object to reach the ground? Numeric : A numeric value is expected and not an expression. %3D

A group of students in a science class monitored the movement of a cat walking along with a straight line and recorded the cat's position in five-second intervals.The results are summarized it in the table below.  time and position time(s) position (cm) 0 49.0 5 38.0 10 43.0 15 40.0 20 60.0   A. What is the displacement of the cat between t = 5.00 s and t = 20.0 s?   B. What is the average velocity of the cat between t = 5.00 s and t = 20.0 s?   C.What is the distance the cat traveled between t = 5.00 s and t = 20.0 s?

This is the vx-tgraph for an object moving along the x-axis. Which of the following descriptions of the motion is most accurate? Vx The object is speeding up at an increasing rate. The object's speed is changing at a steady rate. O The object is slowing down at an increasing rate. The object is slowing down at a decreasing rate. The object is speeding up at a decreasing rate.

Velocity Problem 1. The position of an object is given as a function of time as x(t) = (3.0 m/s)t + (2.0 m/s2)t2. What is the average velocity of the object between t-0.0s and t = 2.0 SP

Problem 2 experiment produced data whose curve-fit particle acceleration was approximated by the equation a = 30 – 3t², where a and t are expressed in ft/s² and seconds, respectively. The particle starts at t = 0 with v = 0 and x = 12 ft. (a) the time when the velocity is again zero, (b) the position and velocity when t = 6 s (c) the total distance traveled by the particle from t = 0 to t = 6 s. Determine: %3D

an object has a velocity of (5.4 m/s)i - (5.8 m/s)j. over a period of 1.3 s, its velocity changes to (1.7 m/s)i + (5.9 m/s)j. What is the displacement

A motorcycle officer hidden at an intersection observes a car driven by an oblivious driver who ignores a stop sign and continues through the intersection at a constant speed. The police officer takes off in pursuit 2.0s after the car has passed the stop sign. She accelerates at 4.2 m/s^2 until her speed is 110 km/h until she catches the car. The car is 1.4 km from the intersection. a) How long did it take for the officer to catch the car? b) How fast was the car traveling?

You get in your car and drive north, accelerating up to 60mph. Draw your velocity vector and acceleration vector some time during your acceleration. How would these change if you encountered traffic and started to brake?
