El conductor de un auto que se mueve a 108km/hr reacciona los frenos y logra detenerlo en 60mts ¿Cuál fue la desaceleración que aplicó el conductor?

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a. true or b. false

Suppose you plot the distance traveled by an object at various times and you discover that the graph is not a straight line. what does this indicate about the object's acceleration?

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
