Q1. A snowmobile climbs a hill at velocity v-up. The slope of the hill is a 2 ft rise for every 70 ft of distance. The resistive force of the snow is equal to 4.12 percent of the weight of the snowmobile. How fast will the snowmobile move downhill, assume the engine delivers the same power?
Q2. How many 116 W lightbulbs can you use in a 133 V circuit without tripping a 17 A circuit breaker? (The bulbs are connected in parallel that means that the potential difference across each lightbulb is 124 V.)
