A block of mass m is in contact with the cart C as shown in the figure.
The coefficient of static friction between the block and the cart is μ. The acceleration α of the cart that will prevent the block from falling satisfies : |
\(\alpha < \frac{g}{\mu}\) \(\alpha > \frac{mg}{\mu}\) \(\alpha > \frac{g}{\mu m}\) \(\alpha \geq \frac{g}{\mu}\) |
\(\alpha \geq \frac{g}{\mu}\) |
μmα ≥ mg \(\alpha \geq \frac{g}{\mu}\) |
