Answer:B
y=13cos(1/13x)+13
Step-by-step explanation:
1-5/8=3/8
If he had 5/8 leftover, then he used 3/8.
Answer:
<u>67 m/s</u>
Step-by-step explanation:
Formula for range :
- u = initial velocity
- θ = angle of launch
- g = gravitational acceleration
Solving with the given values :
- 400 = u² x sin60° / 9.8
- u² x √3/2 = 3920
- u² = 7840/√3
- u² = 4526.4
- u = <u>67 m/s</u> (approximately)
