Now if I use the same catapult to throw a large pumpkin will it travel as far as the apple did? Why?
No, as the pumpkin has a larger mass and with the same force it will travel less distance as mass and acceleration are inversely related.Force remains same.

Suppose that a sled is accelerating at a rate of 2 m/s2. If the net force is tripled and the mass remains the same, then will acceleration increase or decrease?
acceleration will increase

Suppose that the force exerted on a lawn mower is increased from 50N to 75N.The mass of the mower remains the same.Will the acceleration increase or decrease?
Here, mass remains the same so as Force increases acceleration increases.

In F=ma, if mass is constant how does acceleration change due to changes in force?
If Force increases ,acceleration increases.
force and acceleration are directly related

In F= ma, how is mass and acceleration related if force is constant?
when mass increases acceleration decreases and when mass decreases acceleration increases.
they are inversely related.

What would happen if I use a catapult instead of my hands to throw an apple? Will the apple travel farther than when thrown by hand?Why?
Yes, as catapult has larger force and hence more acceleration.Force and acceleration are directly related.
Mass of apple remains same .
