Describe the difference between a scientific law and a scientific theory

The following are the differences between scientific theory and scientific law:  

Scientific Theory: A scientific theory is an elaboration of a perspective of the physical environment that can be frequently experimented and validated in accordance with the experimental arrangement, using affirmed obligations of observation, analysis, and evaluation of effects.

In other words, every scientific law is a description based on revolved laboratory measurements that illustrate some features of the World. The scientific laws are actually the summary that has been already proven.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
