t^2=2d/g
t= square root of (2d/g)
Trial 1: t= square root of (22 cm/9.8 m/s^2)
t= square root of (0.22 m/9.8 m/s^2)
t= square root of (0.02245 s^2)
t= 0.15 s
Trial 2: t

Experiment 1: Distance Traveled by a Projectile
In this experiment, you will use kinematic equations to predict the range of a projectile set in
motion. To do this, you will roll marbles down a ramp and off a table to observe vertical and
horizontal motio

Experiment 2: Squeeze Rocket Projectiles
In this experiment, you will investigate how the launch angle of a projectile affects the
distance it travels.
Materials
Masking Tape
Mirror Support
Printer Paper
Protractor
4 Squeeze Rockets
1 Squeeze Rocket Bulb

If a bullet is shot horizontally at the same time another bullet is dropped, neglecting air
resistance, the bullets will hit the ground at the same time. Independence of vector
components means that the horizontal vector does not affect the vertic

Lab reports should be written in the third person. They should include a picture of ones lab set
up and be prepared in the format stated by the lab manual. WebAssign assignments have help
available to help one complete the assignments and are esse

Experiment 4: Density of the Mass Set
In this experiment, you will be become familiar with the mass set.
Materials
Mass Set
10 N Spring Scale
Vernier Caliper
Procedure
1. Use the Vernier caliper to find the height of the 100 g mass (from the mass set).
