Abowling ball of mass m=1.7kg is launched from a spring compressed by a distance d=0.31m at an angle of theta=37 measured from the horizontal. it is observed that the ball reaches a maximum height of h=4.9m, measured from the initial position of the ball. let the gravitational potential energy be zero at the initial height of the bowling ball.
part a) what is the spring constant k, in newtons per meter?
part b) calculate the speed of the ball, v0 in m/s, just after the launch.

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
