Answer:
The linear velocity of the racquet at the point of contact with the ball is 6 m/s.
Explanation:
Given;
angular velocity of the racquet, ω = 12 rad/s
distance of strike, r = 0.5 m
The linear velocity of the racquet at the point of contact is given by;
V = ωr
V = (12)(0.5)
V = 6 m/s
Therefore, linear velocity of the racquet at the point of contact with the ball is 6 m/s.

Image result for Find by means of a vector diagram the resultant of two forces of 7N and 3N acting at right angle to one another
The resultant of two forces of 7N and 3N acting at a right angle to one another is √58 N. Explanation: Let the magnitude of the force of 7N be denoted as “F₁” on the x-axis and the magnitude of the force of 3N be denoted as “F₂” on the y-axis.Oct 22, 2019
Explanation:
So long as an object is accelerating, it means there is an unbalanced force acting on it.
Force = mass * acceleration
F = ma
F = (6)(9)
F = 54N
You can't tell from that information. The center of mass is ALWAYS there, and it has nothing to do with how they're moving.
