Answer:

7.13781 m/s

Explanation:

X-direction | Y-direction

$x=v_{xo}t+\frac{1}{2}a_{x}t^2$ | $y=v_{yo}t+\frac{1}{2}a_{y}t^2$

$3.41=v_{o}cos(28.4)t$ | $0.397=v_{yo}sin(28.4)t+\frac{1}{2} (-9.81)t^2$

$3.41=v_{o}(0.87964)t$ | $0.397=v_{yo}sin(28.4)(\frac{3.87658}{v_{o} })+\frac{1}{2} (-9.81)(\frac{3.87658}{v_{o} })^2$

$\frac{3.41}{0.87964}=v_{o}t$ | $0.397=1.84379-\frac{73.71171}{v^2}$

$\frac{3.87658}{v_{o} } =t$ | $7.13781=v$

Answer:

Conduction, convection, and radiation

Explanation:

Conduction is the process in which energy is transferred from a hot body to a cooler body. Convection is a process by which heat is transferred as a result of the movement of heated fluid in the form of air or water. Radiation refers to the transmission of energy through a material medium.

Based on the information provided, a lava lamp could be used to provide an example of conduction, convection, and radiation.
