Answer:
The velocity of the ball relative the racquet is 15 m/s.
Step-by-step explanation:
Given;
velocity of the tennis ball, = 30 m/s
Velocity of the racquet swung in opposite direction, = 15 m/s
The velocity of the ball relative the racquet () is calculated as;
Therefore, the velocity of the ball relative the racquet is 15 m/s.
-6.5(n-5)=18.2
Use Distributive Property:
-6.5n + 32.5 = 18.2
Subtract 32.5 from both sides:
-6.5n = -14.3
Divide both sides by -6.5
n = -14.3 / -6.5
n = 2.2
Answer:
k=3
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In this problem we have
therefore
The constant of proportionality is k=3
