If I could get help with this question I would be so thankful! 4. Consider the three situations depicted below. In all three situations, System 1 is essentially identical to the setup you used in the lab. System 2 is identical to system 1 except that both blocks are on the frictionless table and a horizontal force of magnitude mig is applied externally to block B. System 3 is identical to system I except that the frictionless table is replaced with a frictionless incline. (In this situation, when the blocks are released from rest, block B accelerates downward.) Frictionless table Frictionless table System 1 System 2 Frictionless incline System 3 Is the magnitude of the acceleration of each block in system 1 greater than, less than, or equal to the magnitude of the acceleration of each block in system 2? Explain your reasoning. a. Is the magnitude of the acceleration of each block in the magnitude of the acceleration of each block in stem 3? system 1 greater than, less than, or equal to b. tude of the acceleration of each block in system 3? Explain your reasoning. Explain your reasoning.

Explanation / Answer

here,

accelration = net force on the system/(total mass)

a.

accelration of system 1 , a1 = mB*g/(mA + mB)

accelration of system 2 , a2 = mB*g/( mA + mB)

therefore both the accelrations are equal

the magnitude of accelration of system 2 is equals to the magnitude of accelration of system 1

b.

accelration of system 1 , a1 = mB*g/(mA + mB)

accelration of system 3 , a3 = (mBg - ma*g*sin(theta))/(mA + mB)

therefore , a3 < a1

the magnitude of accelration of system 3 is less than the magnitude of accelration of system 1
