The equation for this is very simple you add then you subtract then you get the answer then you divide then it all works out for you
Answer:
40m/s
Explanation:
The horizontal component of velocity remains constant because there are no external forces in that direction
By applying motion equations, V= U+ at
where ,
- v - final velocity
- u - initial velocity
- a-acceleration
- t - time
v = u +at
As no force act on the ball ( we neglect air resistance here) no acceleration is seen,
So v = u = 40m/s
Answer:
C 2000v its obviously ans because if o is 1000 2 vo is 2000v
