QUESTION #1:if there were no gravity a ball thrown upward at an angle would follow a straight-line path. Due to gravity, however, at the end of 1 s it is?a.) 5 m below the straight lineb.) 10 m below the straight linec.) 15 m below the straight lined.) 20 m below the straight line QUESTION #2:if there were no gravity a cannonball fired upward at an angle of 45 degrees would follow a straight-line path. Due to gravity, however, at the end of 3 s it is?a.) 5 m below the straight lineb.) 10 m below the straight linec.) 20 m below the straight lined.) more than 20 m below the straight line

The acceleration of the gravity is 9.81 meters per second per second. Assuming is falling from rest then it will have fallen from the straig light approimately:

[tex]\begin{gathered} y=-\frac{1}{2}gt^2 \\ y=-\frac{1}{2}(9.81)(1)^2 \\ y=-4.905 \end{gathered}[/tex]

Therefore the answer is a.

Q2.

In this case the time is 3 s. then we have:

[tex]\begin{gathered} y=-\frac{1}{2}(9.81)(3)^2 \\ y=-44.145 \end{gathered}[/tex]

Therefore the answer is d.
