A50.0-g super ball traveling at 27.0 m/s bounces off a brick wall and rebounds at 16.0 m/s. a high-speed camera records this event. if the ball is in contact with the wall for 3.90 ms, what is the magnitude of the average acceleration of the ball during this time interval?

We can use kinematics to find the average acceleration. Let v0 = -27.0 m/s and let vf = 16.0 m/s. vf = v0 + at a = vf - v0 / t a = 16.0 m/s - (-27.0 m/s) / 3.90 x 10^{-3} s a = 43.0 m/s / 3.90 x 10^{-3} s a = 1.10 x 10^4 m/s^2 The average acceleration during this time interval is 1.10 x 10^4 m/s^2

The answer is a 0.64 volts

Answer

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

explanation

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
