distance traveled by a uniformly accelerated bike is given as

here we know that



now we will have from above equation


so it will cover the total distance of 300 m
The formula to find work is

. In this case, the force exerted on the rock is 15 Newtons and the distance the rock moved was 2 meters, so 15 * 2 = 30. The answer to your question is
D) 30 n-m.
89 degrees Fahrenheit would be 31.7 degrees Celsius!
