The acceleration of a particle moving only on a horizontal xy plane is given by modifyingabove a with right-arrow equals 5t modifyingabove i with caret plus 6t modifyingabove j with caret, where modifyingabove a with right-arrow is in meters per second-squared and t is in seconds. at t = 0, the position vector modifyingabove r with right-arrow equals left-parenthesis 29.0mright-parenthesis modifyingabove i with caret plus left-parenthesis 45.0mright-parenthesis modifyingabove j with caret locates the paticle, which then has the velocity vector modifyingabove v with right-arrow equals left-parenthesis 5.50 m/s right-parenthesis modifyingabove i with caret plus left-parenthesis 3.10 m/s right-parenthesis modifyingabove j with caret. at t = 5.20 s, what are (a) its position vector in unit-vector notation and (b) the angle between its direction of travel and the positive direction of the x axis?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
