Question

Two blocks are connected by a string as in (Figure 1) .

Part A

What is the upper block's acceleration if the coefficient of kinetic friction between the block and the table is 0.26?

Express your answer to two significant figures and include the appropriate units.

Two blocks are connected by a string as in (Figure 1) .

Part A

What is the upper block's acceleration if the coefficient of kinetic friction between the block and the table is 0.26?

Express your answer to two significant figures and include the appropriate units.

2.0 kg Pulley 1.0 kg

equation of motion of 1 kg block

mg - T = ma

1 * 9.8 - T = 1 * a ---------(1)

eqyation of motion of 2 kg block

T - k * mg = ma

T - 0.26 * 2 * 9.8 = 2 * a ---------(2)

on solving equation 1 and we'll get

a = 1.568 m/s^2

acceleration of the block = 1.568 m/s^2
