I'll give a medal for your help!

Answer 1

is answer A ?

Answer 2

answer is c. surely.

Answer 3

\[\int\limits\limits Fdt = \Delta P = m(v_{2}-v _{1})\]

\[\int\limits Fdt =\] area under F-t graph = 4

\[4 = 1 (v _{2}-1) \implies v _{2} = 5\]

Answer 4

What does \[\Delta P\] mean? Also, what is the point of having \[\int\limits_{?}^{?} F \]?

Answer 5

\[\Delta P =\] change in momentum.

Answer 6

its a formula derived by newtons laws of motion.
