Aroller coaster accelerates at a rate of - 3 m/s ^ 2 from 25 m/s at the bottom of a hill to 10 m/s s at the top how long does it take the coaster to reach the top of the hill ?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
