A tennis ball is thrown vertically upward with an initial velocity of +7.0 m/s.
What will the ball’s velocity be when it returns to its starting point? The acceleration of gravity is 9.81 m/s^2.

Answer in units of m/s

AND How long will the ball take to reach its starting
point?

Answer in units of s

  • Physics -

    its velocity will be 7 m/s. because the velocity of a vertically projected body remains same at the point of projection even if it is in down ward direction.
