Mike and Brandon carry a log that weighs 644N. The trunk is 8.2m long and its weight is evenly distributed (you can consider the center of mass right in the middle). If Mike is 1.5m from the left end and Brandon is 2.9m from the right end, find the force that Mike has to exert to keep the trunk in balance. He considers that both Mike and Brandon exert forces directed completely upwards. Write the result in Newtons with two decimal places.

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

During a car accident, a 125kg driver is moving at 31m/s and in 1.5s is brought to rest by an inflating air bag. what is the magnitude of the change in momentum to the driver
