A child throws a ball with a speed of 5 feet per second at an angle of 73 degrees with the horizontal. Express the vector descri bed in terms of i and j.
1 answer:
Answer:
v = 5cos(73°)i +5sin(73°)j
Step-by-step explanation:
The components of the velocity vector are ...
horizontal (i direction): 5·cos(73°)
vertical (j direction): 5·sin(73°)
Then the velocity vector is the sum of these component vectors:
v = 5cos(73°)i +5sin(73°)j
