What are the si units for work?

a. calories
b. watts
c. ergs
d. joules

Joules is the SI units for work.

 Option D

Explanation:

In the metric system, which is a common nomenclature for the standard representation of measurements to avoid confusions and errors, the unit of work is joule.

Work is referred as the amount of energy spent by a force. SI stands for International system of units. Option A,B and C are irrelevant because watts is used to represent power, and calories are used to represent the energy spent.

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
