Answer 2

Explanation:

v=u-gt ( v=final velocity, u=initial velocity, g=acceleration due to gravity, t=time taken)

v=15-(9.8*2)

v=15–19.6

v=—4.6m/s

Also, (v^2)—(u^2)=2gh (h=total distance covered in air)

(—4.6^2)—(15^2)=2*(-9.8)*h (g is -ve cuz ball is thrown against gravity)

21.16–225=-19.6*h

h=203.84/19.6

h=10.4 m
