Answer:
27 km/h (｡◝‿◜｡)
Step-by-step explanation:
Let's take the direction in which Diego is travelling as positive direction. Therefore:
- Diego is travelling at a velocity of +7 km/h, towards the net
- The ball travels at +20 km/h towards the net, with respect to Diego's reference system
Therefore, the velocity of the ball with respect to the net reference system is equal to the sum of the two velocities:
Answer:
Step-by-step explanation:
Given
Perpendicular to
Pass through
Required
Determine the line equation
First, we need to determine the slope of
An equation is of the form:
Where
In this case:
Next, we determine the slope of the second line.
Since both lines are perpendicular, the second line has a slope of:
Since this line passes through (-2,2); The equation is calculated as thus:
Where
This gives:
Add 2 to both sides
