14.On planet #4, you fire a projectile from the ground at an initial speed of 66.1 m/s at an angle of 49.2 degrees above the horizontal. The projectile lands 25.7 m away from the launch point. What is the value of g for planet #4? 7.6 m/s^2 168.2 m/s^2 128.7 m/s^2 9.9 m/s^2 15.On planet #5, a stone dropped from a height of 30.6 m above the ground will hit the ground at a speed of 57.3 m/s.

Need help With Analysis questions.
Ballistic Pendulum Lab In this lab, you will explore
conservation of Energy and Momentum in an inelastic collision
between a projectile and a cardboard box suspended from a string.
In particular, you will see that the transfer of linear momentum is
easily accounted for in an inelastic collision, but the transfer of
kinetic energy is not easy to measure directly. This is because
Kinetic Energy in collisions transfers to vibrational, acoustic,
and potential energy. Once...

I need help for numbers 1 and 3. For number one I
measured the height of the track at angle. One of the heights was
.082m. hypotenuse 1.013m. I did sin^-1(.082/1.013) and got 4.64
degrees. I used a sensor and aquired data for change in v and t as
a glider fell down the track. I calculated the acceleration at that
height and angle as -10.18 m/s^2. final V was 1.48, initial V .687.
final t=.0675, initial t= .1454.
