Ken griffey jr hits a baseball so that it leaves the bat with an initial speed of 37 m/s at an angle of 53.1 degrees above horizontal. when the ball is hit, it is 1.07 m above the ground. how much total time is does the ball spend in the air before hitting the ground? what is the maximum height of the ball relative to the ground? how far does the ball travel?

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

What is the final velocity of the initial velocity of 25 and -50?
