For a top player, a tennis ball may leave the racket on the serve with a speed of 55 m/s (about 120 mi/h). if the ball has a mass of 0.060 kg and is in contact with the racket for about 4 ms (4 x 10-3 s), estimate the average force on the ball. would this force be large enough to lift a 60-kg person?

Yes is large enough

Explanation:

We need to apply the second Newton's Law to find the solution.

We know that,

And we know as well that

Replacing the aceleration value in the equation force we have,

Substituting our values we have,

The weight of the person is then,

We can conclude that force on the ball is large to lift the ball

i need the answer to this too but idk it ; -;

pe = weightxheight = 2000x1000=2,000,000joules
