A 32 -kg block is attached to a spring and can move without friction in a slot as shown. The block is in its equilibrium position when it is struck by a hammer that imparts to the block an initial velocity of $250 \mathrm{mm} / \mathrm{s}$. Determine $(a)$ the period and frequency of the resulting motion, (b) the amplitude of the motion and the maximum acceleration of the block.

At the instant shown, the tensions in the vertical ropes $A B$ and $D E$ are $300 \mathrm{N}$ and $200 \mathrm{N}$, respectively. Knowing that the mass of the uniform bar $B E$ is $5 \mathrm{kg}$, determine, at this instant, $(a)$ the force $P,$ (b) the magnitude of the angular velocity of each rope, $(c)$ the angular acceleration of each rope.

INSTANT ANSWER

The following statements are known to be true. Use logic and/or Truth Tables to determine whether or not “whales have short tail”. It’s not the case that either my house is blue or John’s van is red. My cat Luna is unhappy. If Sunday are cloudy then Luna is happy. Either pencils are yellow or Sunday are cloudy or John’s van is red. If whales have short tail then pencils are not yellow.
