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.

This graph shows the position of a particle as a function of time. What is its instantaneous velocity at t = 7 s? x (m), 12 1(s) 6. 2 O 3 m/s -3 m/s O 12 m/s O -12 m/s O Need additional information

An object moves in the x-y plane with a constant acceleration of 2i +3j meters per second squared. The object starts at the origin with some initial velocity. After four seconds (4 seconds) the velocity of the object is 2i + 8j meters per second. Determine the object’s initial velocity. Leave answer in i-j notation. Determine the position of the object at time, t = 4 seconds. Leave answer in i-j notation.   Thank you for your help.

A ball moves along a 1D coordinate system with the following motion parameters at time t = 0 s: x₁ = 1.9 m and vo = 0 m/s. The ball has a constant acceleration of 1.1 m/s2 during the entire motion which occurs over a time of 1.2 s. Assume that an error in position of 4% is acceptable in this application over the entire motion. How many rows N will be needed in the table to model the entire motion to within the required error even though you are leaving out the final term of 1/2 a (At )²) present in the exact position expression?
