Answer:
4.56 s
Explanation:
Let t (seconds) be the time it takes from the moment when the motorcycle starts to accelerate until it catches up with the car. Since prior to this they are traveling at constant speed, they would have maintained a distance of 52 m before accelerating.
The distance traveled by the car, with respect the motorcycle position when it start accelerating is
The distance traveled by the motorcycle after accelerating, with respect the motorcycle position when it start accelerating is
When the motorcycle catches up to the car, their position are at the same
Heat required to raise the temperature of water is given as
here we have
m = 100 g = 0.100 kg
s = 4183 J/kg C
now we can use the above equation
so here it requires 20920 J heat to raise the temperature of 100 g water by 50 degree C
