Design Project Report

This document describes a design project to create an electric cart that can launch a ball vertically when hitting a wall. The cart must travel 2 meters and hit a 2 meter high wall using projectile motion calculations and Hooke's law. A conclusion states that the cart meets all specifications of being able to travel 2 meters using mechanical techniques to launch a projectile without electronics. Recommendations include using more rubber bands to improve the projectile and adding bottle lids as stabilizers for better wheel alignment.

Abstract
In the report we were so supposed to make at cart, that will be able to move with using and
electric power. So, after all of that is achieved, we must find a way to make something will be
attached to the cart which will carry a ball which is to be launched a vertically upward when the
ball hit the wall. The cart must have a power to travel two meters distance and hit on the wall
of also two meters in height. This to be achieved will have to apply the laws of projectile motion
to calculate the amount of power we need for the cart to travel that type of distance and
hooker’s law to make the cart to move with out power. They another this that need to be
considered like the mass of the material used, balance and the friction in which the cart will be
on motion to.

Design Proposal
Conclusion
The goal of this project was to develop a design and a prototype for Projectile Cart. The vehicle
supposed to carry a mechanism that will launch a projectile. The most important specifications,
the Cart must be in motion using mechanical techniques, no electricity is required. The
triggering mechanism for a projectile launcher must be designed using mechanical technique’s,
no electronic sensors are needed. The vehicle was made to be light as possible to be able to
travel 2m using rubber bands. The Design meets the purpose of it and all specifications.

Recommendations
Our mini cart is made for speed. Its design is made such that it is aerodynamic,
the front of the mini cart is lower than the rear. This is achieved by having small
wheels at the front and big wheels at the rear. The way that it moves is through
rubber bands tied to the back axle and winded up and then released.
The way we can improve the cart is using more rubber bands for the projectile.
For the wheels the alignment is not so great. For the alignment we could use
stabilizers such as bottle lids to make it stable.
