A ball is thrown vertically upward by a cricket player with an initial velocity of 40 m/s. if motion of ball accelerated by 10 m/s^2, then calculate 1) the maximum height reached by the ball
2) the distance covered by the ball when it reaches the player's hand
3) the displacement covered by the ball when it reached player's hand

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

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.
