Answer:
22.8 m/s at 17.4°
Step-by-step explanation:
Horizontal component:
vₓ = 3 + 20 cos 20° = 21.8
Vertical component:
vᵧ = 0 + 20 sin 20° = 6.84
Magnitude:
v² = vₓ² + vᵧ²
v² = (21.8)² + (6.84)²
v = 22.8 m/s
Direction:
θ = atan(vᵧ / vₓ)
θ = atan(6.84 / 21.8)
θ = 17.4°
Answer:
3.2
Step-by-step explanation:
12 4/5 times 1/4= 3 1/5 or 3.2
Answer:
9 because 3:7 means that for every 3 lemons she buys there's 7 apples being bought so you'd add 3+7 until it equals 30 and that's your answer which here is 9 Lemons.
Answer:
