A car traveling initially at 8.46 m/s acceler- ates at the rate of 0.963 m/s2 for 5.63 s.
What is its velocity at the end of the accel-
eration?

f is prop to m1xm2 double m1 double force

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
