A physics student on another planet throws a ball that follows aparabolic trajectory.
At t = 1 s, the velocity is given by â¬v? = (2iË + 2Ëj )m/s. At t =2 s, the ball reaches its highest point. Determine the velocity att = 0, 2 s, and 3 s. Determine the value of g on this planet.
3. A projectile is launched over level ground at an initial angle ?above the horizontal.
An observer standing at the launch site sees the projectile at itsmaximum height and
measures it to be an angle f above the horizontal. Beginning withkinematic equations, prove that tanf = 12tan? .
