Practice Test 4

Based on the scenario described, a $10,\text{kg}$ crate on a level floor with $\mu_k=0.30$ moves at constant velocity; determine the required horizontal pull.

Based on the scenario described, calculate the acceleration of a $1.5,\text{kg}$ puck with $\vec F_1=6,\hat\imath,\text{N}$ and $\vec F_2=-3,\hat\imath,\text{N}$ applied.
