Question 1 Correct 5.00 points out of 5.00 A 0.200 kg dart is fired horizontally at a speed of 2.75 m / s when it hits a 0.700 kg block ofwood suspended by a string. The nose of the dart sticks into 0.00210 m the wood. Together the dart and block swing upwards from a height of 0.0500 m above a table to 0.128 m above the table. Which of the following is the average force the dart applies to the block during impact? Select one: a. 32.4 N b. 15.1 N c. 1.36 N d. 0.872 N Straighterl...

Emergency Vehicle Operations (EVOC) Questions and Answers Already Passed Three (3) main factors that directly impact basic motor vehicle operations are: -Vehicle -Driver -Roadway Laws of Physics: 1) Kinetic energy Energy an object possesses by being in motion. 2) Momentum Is the combined mass and velocity of an object. An object in motion tends to remain in motion until acted upon by an outside force. 3) Friction Is resistance between two objects rubbing against each other. * Rolling Frictio...
