A baseball player swings at a 0.15 Kg baseball and accelerates it at a rate of 30,000 m/s/s. The bat contacts the ball for 0.057 seconds. With what speed does the ball leave the bat? (assume the initial speed is 0, it is on a tee)

(the force is 4.5 × 10^-3 N)​

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

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
