Constants | Periodio Part A An electron has an initial velocity vo = (6.0 x 104 m/s) i Determine the vector acceleration of the electron as a function of time. It enters a region where E = (2.5i + 8.8j) x 104N/C. Express your answer using two significant figures. Enter the x and y components of the acceleration separated by a comma. az, ly = m/s? Submit Request Answer Part B At what angle 6 is it moving (relative to its initial direction) at t = 1.6 ns ? Express your answer using two significant figures.

What graph represents the y-component of acceleration versus time?

QUESTION 15 If the velocity of an object is zero at some point, then its acceleration must also be zero at that point. O True O False QUESTION 16 Suppose that an object travels from one point in space to another. Make a comparison between the magnitude of the displacement and the distance traveled by this object O A. The magnitude of the displacement can be either greater than, smaller than, or equal to the distance traveled. O B. The magnitude of the displacement is either less than or equal to the distance traveled OC The magnitude of the displacement is always equal to the distance traveled. O D. The magnitude of the displacement is either greater than or equal to the distance traveled.

1. Isaac can throw a baseball to a maximum height of 28.6 m above the ground. What is the speed of the ball when it hits the ground? m/s What is the total time of flight of the ball if Isaac releases the vertical throw 2.15 m above the ground? s What was the initial velocity of the throw? m/s If Isaac then took a trip to the Moon where 2 the acceleration due to gravity is 1.62 m/s and threw the baseball vertically with the same initial velocity and release point, what would be the maximum height the ball would travel above the Moon's surface?
