Question

Part A A delivery company has unloaded a \( 30 \mathrm{~kg} \) crate in your driveway. The coefficient of static friction between the crate and the driveway surface is \( \mu_{\mathrm{s}}=0.40 \). The coefficient of kinetic friction is \( \mu_{\mathrm{k}}=0.30 \). In order to move the crate, you apply a horizontal force of magnitude \( F \) by pushing on it. As a result, the crate slides with an acceleration of \( 2.0 \mathrm{~m} / \mathrm{s}^{2} \). What is the force \( F \) ? Express your answer with the appropriate units.

Part A
A delivery company has unloaded a 30 kg crate in your driveway. The coefficient of static friction between the crate and the driveway surface is μs=0.40. The coefficient of kinetic friction is μk=0.30. In order to move the crate, you apply a horizontal force of magnitude F by pushing on it. As a result, the crate slides with an acceleration of 2.0 m / s^2. What is the force F ?
Express your answer with the appropriate units.
