Answer:
(A). The horizontal initial velocity is 25 m/s.
(B). The vertical initial velocity is 43.3 m/s.
(C). The velocity component is
Explanation:
Given that,
Initial velocity = 50.0 m/s
Angle = 60°
We need to calculate the component of velocity
Using formula of component
(A). Horizontal initial velocity
Put the value in to the formula
(B). Vertical initial velocity
Put the value in to the formula
The velocity component is
Hence, (A). The horizontal initial velocity is 25 m/s.
(B). The vertical initial velocity is 43.3 m/s.
(C). The velocity component is
Answer:
The magnitude of air = 392N
Explanation:
We use Newton's 2nd law. The sum of the vertical forces must be equal to zero because at terminal speed , the acceleration is zero. Solving for the air resistance force,F(air ) gives:
EFvertical = mg - F(air)= ma
F(air) = mg = 40 × 9.8 = 392N
Answer:
Both eggs are identical. The aim is to find out the highest floor from which an egg will not break when dropped out of a window from that floor. If an egg is dropped and does not break, it is undamaged and can be dropped again. However, once an egg is broken, that's it for that egg.
10 x 4^2 = 160 / 8..
V = 20m/s...
...x 8 = 100 miles,meters, metric what ever m stands for after 8 seconds.
This is my guess since the problem says 4m/s^2
V= distance/ ST (traveled/used)
Answer:
Vd = 0.022 (V)
Explanation:
What we have as voltage drop is the difference between the voltage at source level (terminals) and the voltage at the terminal of electrical load ( in this case the toaster oven) that difference occures as consequence of the normal distributed resistance of conductor. But the voltage at the terminal of the electric load have to be measure between the two wires at the end of the circuit.
Therefore the voltage drop is = I*R = 11 (A) * 0,002 Ω = 0.022 (v)
