Project Nerf The Experiment Goal: The goal of this experiment is to determine the velocity of a Nerf projectile. Begin Testing Set up the gun on wooden stool (.85 meters tall)

Taped gun at a 45 degree angle (using wooden blocks)

Laid tape on the floor and laid tape measure next to it 0 m-9 m

Two people watched where the bullet landed

One person recorded distance Testing and Results We tested bullets A, B, and C each 100 times.

Average Distance Velocity Time

Bullet A 7.84 m 8.44 m/s .9 s

Bullet B 8.11 m 8.56 m/s .9 s

Bullet C 7.93 m 8.46 m/s .9 s Conclusion Bullet A: Bullet B: Bullet C: Hypothesis: If three different bullets are shot out of the same Nerf gun, each bullet will travel a different distance and have a different velocity. Determining the Velocity of a Nerf Projectile Bullet B traveled the farthest and had the fastest velocity.

The velocities of Bullets A and C were nearly identical.

The time for all three bullets was nearly the same.

We concluded that the head weight of the bullet does make

a difference regarding the velocity and total distance each

bullet travels. Statistical Analysis Standard Deviation How we found velocity We found velocity and time using the following two equations: Dy= Viyt + 1/2Ayt² Dx= Vxt or t=Dx/Vx Diagram Variables Dx=average distance

Dy=.85 m

θ=45° Vx=vcosθ=vcos45°=.7v

Vy=vsinθ=vsin45°=.7v

Ay=9.8m/s^2 Mean Median Mode

Bullet A 8.44 8.68 8.44

Bullet B 8.56 8.975 9.04

Bullet C 8.46 8.83 8.52 Bullet A
