Question

In the figure below, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T3 = 70.4 N

(a) If m1 = 11.0 kg, m2 = 23.5 kg, and m3 = 30.5 kg, calculate the magnitude of the acceleration of the system.

(b) Calculate the tension T1.

(c) Calculate the tension T2.

In the figure below, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T3 = 70.4 N. T, Tz Ts m2 m3 (a) If m,-11.0 kg, m2 23.5 kg, and m-30.5 kg, calculate the magnitude of the acceleration of the system. m/s? m/s2 (b) Calculate the tension T1. N (c) Calculate the tension T2 N

Explanation / Answer

a)

let the acceleration is a

a = 70.4/(11 + 23.5 + 30.5)

a = 1.083 m/s^2

the acceleration is 1.083 m/s^2

b)

for the tension T1

T1 = m1 * a

T1 = 1.083 * 11

T1 = 11.91 N

the tension T1 is 11.91 N

c)
T2 = (m1 + m2) * a

T2 = (11 + 23.5) * 1.083

T2 = 37.4 N

the tension T2 is 37.4 N
