A ball rolls from x = 10 m to
x= -25 m in 2.5 seconds. What was
its average velocity?
(Units = m/s)
Don't forget: velocities and displacements to
the right are +, to the left are -

heats surface water up

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

god i hope this !
