After an average acceleration of 3.01 m/s23.01 m/s2 during 2.97 s2.97 s , a car reaches a velocity of 15.7 m/s15.7 m/s . Find the car's initial velocity.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud

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.
