Acar is traveling east at 15.0 m/s when it turns due north and accelerates to 40.0 m/s, all during a time of 9.00 s. calculate the magnitude of the car's average acceleration (in m/s2).

Solar cell a produces 100 joules of energy, when a light source is shown on it for 3 minutes. solar cell b produces 200 joules of energy when the same light source is shown on it for 5 minutes. which solar cell works better? a) solar cell b, because it produces more energy. b) solar cell b, because it generates more power. c) solar cell a, because it produces energy quicker. d) solar cell a, because it generates a greater wattage. eliminate
