A steel ball of mass 3 kg moving at 2.4 m/s to the left hits a stationary, 4 kg glob of clay. The ball becomes imbedded in the clay. At what speed would the combined object move away?

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .

The direction of the current in an alternating current circuit remains constant. is direct. changes repeatedly. changes randomly.
