The average force of a baseball is 18.9 N. Its mass is 0.145 kg. Find the acceleration.
2.
a 130 m/s2
b

С
75 m/s2
d
110 m/s2

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

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
