Two Blocks having mass m=11.0 kg are connected by a light string passing through two pulleys as shown. The block on the left is resting on an inclined plane of angle 0=45.0° . The pulleys and the planes on which the blocks are resting are frictionless. The blocks are released from rest and allowed to move freely. a. Draw the free body diamgrams for each block and then write down newton's second law of motion for each one separately. b. Find the acceleration of the blocks and the tension in the string.

A rocket with a mass of 2.70x106 kg exerts a vertical force of 3.40×107 N on the gases it expels. ▼ Part A Determine the acceleration of the rocket. Assume g remains constant, and ignore the mass of gas expelled (not realistic). Express your answer using two significant figures. VE ΑΣΦ Submit Dart R Request Answer ? m/s²
