A 100 g block is placed on a horizontal surface. What force, directed horizontally, must be applied to the bar so that it can move with an acceleration of 2 m / s ^ 2.
Initial data: m (weight of the bar) = 100 g (0.1 kg); a (acceleration with which the bar should move) = 2 m / s2; the bar is on a horizontal surface; since the friction force is not indicated, we take it equal to zero.
The horizontally directed force applied to the bar is calculated by the formula: F = m * a.
Calculation: F = 0.1 * 2 = 0.2 N.
Answer: A horizontal force of 0.2 N must be applied to the bar.
