Suppose, a soccer player kicks the ball from a distance 30m toward the goal. find the initial speed of the ball if it just passes over the goal. 2.4m above the ground, given the initial to be 40° above the horizontal

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
