Answer:
20kg
30kg
60kg
120kg
since weight is mass x force,
and gravitational force in earth is 10N;
mass will me weight/force
Explanation:
60 days, tell me if I'm correct please.
The only force acting on the ball, once it left the hand of the player, is the gravitational atraction of the earth. Once the ball reaches its maximum height, it starts a free fall movement under the action of earth's gravity.
Then the magnitude of the acceleration of the ball is the gravitational acceleration, g, approximatley 9.8 m/s^2
