An object initially at rest experiences a constant horizontal acceleration due to the action of a resultant force applied for 10 s. The work of the resultant force is 10 Btu. The mass of the object is 45 lb. Determine the constant horizontal acceleration in ft/s².

A 14-kg rock is thrown upward with a force of 280 N at a location where the local gravitational acceleration is 9.79 m/s². Determine the acceleration of the rock, in m/s2. Solve this problem using appropriate software. Print out the entire solution, including the numerical results with proper units. The acceleration of the rock is m/s²

A 40 lb object is subjected to an applied upward force of 20 lbf. The only other force acting on the object is the force of gravity. The acceleration of gravity is 32.2 ft/s². Determine the weight of the object, in lbf, and the net acceleration of the object, in ft/s². Step 1 Determine the weight of the object, in lbf, with positive values being down. W = 40 lbf Hint Step 2 Your answer is correct. * Your answer is incorrect. Determine the net acceleration of the object, in ft/s², with positive values being upward. 16.1 ft/s² a = Attempts: 1 of 3 used

A 50 lb object is subjected to an applied upward force of 10 lbf. The only other force acting on the object is the force of gravity. The acceleration of gravity is 32.2 ft/s². * Your answer is incorrect. Determine the net acceleration of the object, in ft/s², with positive values being upward. 32.2 ft/s² a =
