Hello, silvercats!

Object is projected with a velocity of 18 m/s and angle of 60 degrees. .Take g=10

What is the (a) flying time, (b) horizontal distance

and (c) the maximum height of the object?

The equations for projectiles are: .

. . where: .

We have: .

Hence: .

. . . . . .

(a) Flying time: When does the object strike the ground?

. . .When

(b) Horizontal distance.

. . . In

(c) Maximum height

. . .The object reaches maximum height in

. . .(Half the flying time.)
