Chapter 6 File Edit View Help Problem: 15 Do not round intermediate answers. Give your final answer(s) to three decimal places. Check your units. (of 29) The uniform square steel plate has a mass of 14 kg and is resting on a smooth horizontal surface in the x-y plane. If a force P 170 N is applied in the x-y plane to one corner in the direction shown, determine the magnitude of the initial acceleration of comer A. Hint: At the initial stage of motion when the plate begins to move,0 because the plate is barely moving. a of A 29.13 m/sec 2 120 120 mm 450 Check Answer for this Problem Close

Explanation / Answer

Since at the initial stage, angular vlocity is zero, the acceleration of A will have only translational component

The translational initial acceleration=P/m, where P is applied force and m is mass of plate

Acceleration=170/14=12.14 m/s²
