Exercise 3-3. 1. Using trigonometry and the dimensions that you measured and recorded in Data Table 1, calculate the angle of the ramp, 6. 2. Calculate the velocitvr at the bottom of the ramp, V ramp ' 3. How do the values of velocitv that the ball began projectile motion with (UL?) compare to the velocity at the bottom of the ramp (V )? ramp 4. Is limp within the 90% confidence interval that you calculated at the end of Exercise 3- 2? 5. Briefly discuss why these values might not be equal
