A 40 N force is applied to a 10 kg block, but the object only accelerates at 2 m/s^2. What is the net force acting on the block? Use a free body diagram to explain your answer.

connect the batteries in series and hope

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

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
