A car takes 4 s to come to rest while traveling 20 m at constant acceleration. Can the speed of the car immediately before the brakes were applied be determined without first determining the car's acceleration?
Yes, by dividing the distance (20 m) by the time (4s).
Yes, by determining the average speed while braking and doubling it.
No, because the acceleration is need to use standard kinematics equations.
No, because the fundamental relationship that defines velocity contains acceleration.

While traveling in an elliptical orbit around the Sun, Mars gains speed when it is closest to the Sun. Which of the following best explains this phenomenon?
As Mars gets closer to the Sun, the Mars-Sun system loses potential energy and gains kinetic energy.
A component of the gravitational force is perpendicular to the direction of motion and causes a gain in speed.
Torque exerted on Mars by the Sun during this segment increases the Mars-Sun system's angular momentum.
The centripetal force exerted on Mars is greater than the gravitational force during this segment of the orbit.
