Amotion sensor is used to create the graph of a student’s horizontal velocity as a function of time as the student moves toward and away from the sensor, as shown above. the positive direction is defined as the direction away from the sensor. which of the following describes the student’s final position xf in relation to the starting position x0 and the student’s average horizontal acceleration ax between 0.0 s and 3.0s? a.)position xf is farther away from the sensor than x0, and ax is positive. b.)position xf is farther away from the sensor than x0, and ax is negative. c.)position xf is closer to the sensor than x0, and ax is positive. d.)position xf is closer to the sensor than x0, and ax is negative.

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
