Wo stationary positive point charges, charge 1 of magnitude 3.35 nc and charge 2 of magnitude 1.55 nc , are separated by a distance of 58.0 cm . an electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. what is the speed vfinal of the electron when it is 10.0 cm from charge 1?
express your answer in meters per second.

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
