Question

a bodybis thrown vertically upward with velocity of 30m/s calculate the the maximum height attained​

Answer 1

Explanation:

• Initial velocity(v)=30 m/s
• Final velocity(u)=0 m/s
• Acceleration due to gravity(g)=9.8m/s²
• Height(h)=?

Now,

By the third equation of motion, we have

• v²=u²+2gh
• 30²=0²+2×9.8×h
• 900=0+19.6h
• 900=19.6h
• 900/19.6=h
• h=45.918 m
