A 1.70-kg aluminum block and a 7.45-kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle ? = 33.0

A 1.70-kg aluminum block and a 7.45-kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle ? = 33.0 degree) as shown in the figure. Making use of the table below, determine the following. the acceleration of the two blocks the tension in the string

Explanation / Answer

(a)
a = (9.80665 m/s^2)[ 7.5 kg)(sin33 - 0.36cos33) - (0.47)(1.7 kg)]/(9.15 kg)


a = 1.09 m/s^2

(b)
T = (1.7 kg)(1.09 m/s^2) + (0.47)(1.7 kg)(9.80665) m/s^2


T = 9.688 N
