Answer

20 m

Step 1: Use the kinematic equation for maximum height where final velocity v=0v=0 m/s.

v2=u2−2ghv^{2} = u^{2} - 2gh

Step 2: Substitute v=0v=0 m/s, u=20u=20 m/s, g=10g=10 m/s2^{2}:

02=(20)2−2(10)h0^{2} = (20)^{2} - 2(10)h 0=400−20h0 = 400 - 20h

Step 3: Simplify to solve for hh:

20h=40020h = 400 h=40020=20 mh = \frac{400}{20} = 20\ m

Final answer: 20 m
