what is the instantaneous acceleration of the particle at point b?

a.

ab

b.

bc

c.

cd

d.

all distances covered in the marked regions are the same.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

unlike poles attract

more than, less

less than, more

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
