+ In the first part of the experiment, one group of students recorded 1.343 m and 0.799 m as their Range and
Height measurements, respectively. What is the marble's initial muzzle speed in m/s unit? Enter your number with correct amount of significant figures, assuming g=9.80 m/s2.
+ For the second part of the experiment, a group of students set their canon up to fire such that instead of striking the ground, the ball strikes the table top. (Take the height of the canon above the table as h=0.00 m). They used 3.29 m/s as the Initial Velocity and 60.0 degree as the elevation angle to calculate the shooting range of the marble. What would be the range in meters? Enter the number with the correct amount of significant figures, assuming g = 9.80 m/s2.
* I keep doing these problems over and over again and I am not entirely sure what I am doing wrong.
