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;
![V_R_B = V_B-V_R\\\\\V_{RB} = 30 \ m/s - 15 \ m/s\\\\V_{RB} = 15 \ m/s](https://tex.z-dn.net/?f=V_R_B%20%3D%20V_B-V_R%5C%5C%5C%5C%5CV_%7BRB%7D%20%3D%2030%20%5C%20m%2Fs%20-%2015%20%5C%20m%2Fs%5C%5C%5C%5CV_%7BRB%7D%20%3D%2015%20%5C%20m%2Fs)
Therefore, the velocity of the ball relative the racquet is 15 m/s.
school is asking us to find the probability of dogs breeding I’m sorry I don’t understand
Cot(-5pi/4)= 1/tan(-5pi/4)
= 1/-1 = -1
2/3-> 4/6
1/2-> 3/6
Subtract
1/6
2/5-> 16/40
1/8-> 5/40
Subtract
11/40
