A ball traveling at 3 m/s East hits a wall and bounces off heading West traveling at 2 m/s. If the change in direction took 0.4 second, what is the average acceleration of the ball?

A.) More information is needed
B.) 2.5 m/s^2 West
C.) 12.5 m/s^2 West
D.) 2.5 m/s^2 East
E.) 12.5 m/s^2 East

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

v patient student

this is poiselle's equation from fluid mechanic in physics. mech eng

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
