Question

How exactly would I find the total amount of energy used for a 60 cm stomp rocket that weighs 13.874 g and was launched at 40 degrees for a total of 2.45 seconds?

I wasn't given the initial velocity or Initial speed.

Answer 1

To find the total amount of energy used for a stomp rocket, we can consider the different forms of energy involved: potential energy, kinetic energy, and work done by external forces.

• Potential Energy (PE):

The potential energy is given by the formula PE = mgh, where m is the mass of the rocket, g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height the rocket reaches. Since the height is not provided in the question, we cannot calculate the potential energy without this information.

• Kinetic Energy (KE):

The kinetic energy is given by the formula KE = (1/2)mv², where m is the mass of the rocket and v is the velocity. Since the initial velocity is not provided, we cannot calculate the kinetic energy without this information.

• Work Done by External Forces (W):

The work done by external forces can be calculated using the formula W = Fd, where F is the force applied and d is the displacement. In the case of a stomp rocket, the external force comes from the stomp or launch mechanism. Without information about the force applied or the displacement, we cannot calculate the work done by external forces.

Unfortunately, without the initial velocity, initial speed, force applied, displacement, or height reached, it is not possible to calculate the total amount of energy used for the stomp rocket. Additional information would be required to perform the calculation.
