Your electric drill rotates initially at 5.13 rad/s.5.13 rad/s. You slide the speed control and cause the drill to undergo constant angular acceleration of 0.327 rad/s20.327 rad/s2 for 4.43 s.4.43 s. What is the drill's angular displacement during that time interval

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
