Answer:
a. Greater the mass, larger the crater
b. Greater the speed, larger the crater
Explanation:
a. They key to answering both questions is understanding that the crater produced by an object is as a result of the force that the object applies when it hits the ground. If it applies a lot of force, a larger crater is produced.
Force is calculated by multiplying mass and acceleration. This means that if either of these is high, the force will be grater and the crater will therefore be larger as well.
Explicitly said, the greater the mass of an object, the larger the size of the crater that it will create.
b. The greater the speed of an object, the larger the size of the crater that it will create as well.
