Question

1. Can someone just double check my results?

For table 1 I needed to find the velocity for each trial.

2. For table 2 I was asked to find horizontal velocity.

3. For table 3 I was asked to find the average time, range, and compute velocity.

Table 1: Timing Data of Ball on Table

Distance between tape strips =  10 inches   in meters = 0.254 m

	Trial 1	Trial 2	Trial 3	Trial 4	Trial 5
Time (s)	.32s	.35s	.50s	.45s	.50s
Velocity (m/s)	0.0079	0.0072	0.0050	0.0056	0.0050

Uncertainty Range =

Table 2: Measurement of Projectile Ranges and Calculated Horizontal Velocities

Height of table surface = 26 inches                        in meters = 0.6604 m

	Trial 1	Trial 2	Trial 3	Trial 4	Trial 5
Range ( in )	6 ½ in	6 ½ in	6 in	6 in	5 7/8 in
Range (m)	0.1651 m	0.1651 m	0.1524 m	0.1524 m	0.1492
Velocity (m/s)	0.0051 (m/s)	0.0047(m/s)	0.0030 (m/s)	0.0030 (m/s)	0.2984 (m/s)

Uncertainty Range =
