1. sketch position-versus-time graphs (x versus i or/versus t) for the following motions.
include appropriate numerical scales along both axes. a small amount of computation
may be necessary.

a. a parachutist opens her parachute at an altitude of 1500 m. she then descends slowly to earth at a steady speed of5 m/s. start your graph as her parachute opens.

b. trucker bob starts the day 120 miles west of denver. he drives east for 3 hours at a
steady 60 miles/hour before stopping for his coffee break. let denver be located at x = 0
mi and assume that the x-axis points to the east.

c) quarterback bill throws the ball to the right at a speed of 15 m/s. it is intercepted 45 m
vay by carlos, who is running to the left at7.5 mls. carlos carries the ball 60 m to
ore. let. r = 0 m be the point where bill throws the ball. draw the graph for the football.

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

Two rigid transformations are used to map δhjk to δlmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k

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
