A cannonball of mass 15 kg is fired vertically upward from a cannon with an initial speed of 20 m/s. The cannonball travels upwa

rd, reaches a maximum height of 40 m, and returns to the ground. Now you decide to shoot a 30 kg cannonball vertically upward using the same cannon. If we assume that all cannonballs leave this cannon with an initial speed of 20 m/s, what maximum height does the 30 kg cannonball reach

Answer:

30kg ball will have equal traveling height with the 15kg

Explanation:

When air resistance is negligible, the mass of the object does not affect the maximum height or the time spent in the air.

So if mass does not affect traveling height when sir resistance is neglected...the 30kg ball will have equal traveling height with the 15kg ball provided they have equall velocities and equal angle if projection.

In this case it has 20 m/s and they are all projected vertically.

alexdok [17]
The electrostatic force is directly proportional to the product of the charges, by Coulomb's law.

F α Qq

If the charges are now half the initial charges: 

<span>F α (1/2)Q *(1/2)q
</span>
F α (1/4)Q<span>q

The new force when the charges are each halved is (1/4) the first initial force experienced at full charge.</span>
