Hi there!
The two main factors influencing gravitational pull are...
1) Distance
2) Mass
Answer:
50°
Explanation:
Projectiles launched at complementary angles have the same range.
Explanation:
Table A: Calculation of Density for Regularly Shaped Solids
Table tennis ball Golf ball
"Mass
(g)"
Diameter (cm)
Radius (cm)
Estimated volume (cm3)
Estimated density (g/cm3)
"Prediction of buoyancy
Circle one."
"Observation of buoyancy
Circle one."
Initial volume of water (cm3)
Final volume of water (cm3)
Change in volume (cm3)
Calculated density (g/cm3)
Error (%)
50m/s
I divided the 200m by 4s (so 200/4) to get 50m per second
