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

2.0 kg Pulley 1.0 kg

Explanation / Answer

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
