Question

a player kick a soccer ball which was any Tally at rest he imported an acceleration of 20 metre per second to to the wall calculate the magnitude of the change in velocity at the Inn 2s is and 5s is

correct answer Brillianist ​

Answer 1

Answer:

hope it's helpful marks me at brainlist

Explanation:

Horizontal range is maximum When angle of projection θ is 45∘

Rmax= gu2= 10202= 40m

Time of flight, T=g2usin45∘=102×20×21=22s

The player can catch the ball before reaching the ground if he covers a distance =40−24=16m in 22s

The velocity of that player must be  =2216=42ms−1
