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.
The answer:
x = 1
Explanation:
If the line is parallel to the y-axis it has no slope, so you would only write down the x-intercept.
8 units to the left and 5 units up.
Just pick any point on the blue triangle and count how many you move to get to that same point on the red triangle.
The value of x from the figure is 30 degrees
<h3>Parallel lines</h3>
Parallel lines are lines that have the same slope and have 0 degrees as the angle between them.
The sum of angle 5 and angle 6 are supplementary. Hence;
m<5 + m<6 = 180
3x - 33 + 123 = 180
3x + 90 = 180
3x = 180 - 90
3x = 90
Divide both sides by 3
3x/3 = 90/3
x = 30
Hence the value of x from the figure is 30 degrees
