To Find: The explanation for the fact that the projectile will travel twice as far as it did before.
Answer to Problem 19E
Thesquaring velocity makes the range four times the original one this shows that the hypothesis is wrong.
Explanation of Solution
Given:
The Janelle fired a projectile and measured the range she hypothesizes that if the magnitude that if the magnitude of the initial velocity is doubled and the angle of the velocity remain the same.
Calculation:
Since, the magnitude of the initial velocity is doubled then the range of the projectile is given by,
In the above equation find the value of
When the initial velocity is doubled the squaring effect of the velocity is doubled and the squaring velocity makes the range four times the original one this shows that the hypothesis is wrong.
