A ball weighing 300 g is thrown at an angle of 60 ° to the horizon with an initial velocity of v = 20 m / s. The modulus of gravity acting on the ball at the upper point of the trajectory is equal to:

Which situation will have the highest resistance? a.long wire and high temperatureb.short wire and high temperaturec.long wire and cold temperaturedshort wire and low temperature

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.
