Answer:
Explanation:
There's a formula for this:
F being force, k being the spring constant, and displacement being the change in x
We are given the force and the spring constant, so this is essentially isolating the Δx term. Do 60N/120N per meter. The newtons cancel out and you get a final answer of Δx = 0.5 meters
TOTAL FLIGHT TIME
Rising Projectile
vi = initial velocity = 58.8 m/s
vf = final velocity = 0
g = gravity acceleration = -9.81 m/s²
t = elapsed time = to be determined
vf = vi + gt
vf - vi = gt
(vf - vi)/g = t
t = (vf - vi)/g
t = (0 - 58.8)/-9.81
t = -58.0/-9.81
t = 5.99 s ≈ 6.00 s
Falling Projectile
vi = initial velocity = 0
vf = final velocity = 58.8 m/s
g = gravity acceleration = 9.81 m/s²
t = elapsed time = to be determined
vf = vi + gt
vf - vi = gt
(vf - vi)/g = t
t = (vf - vi)/g
t = (58.8 - 0)/9.81
t = 58.0/9.81
t = 5.99 s ≈ 6.00 s
t(total) = t(up) + t(down) = 6.00 s + 6.00 s = 12.0 s Total Flight Time
HORIZONTAL DISTANCE TRAVELED
v = velocity, horizontal = 20.0 m/s
d = to be determined
t = elapsed time = 12.0 s
v = d/t
vt = d
d = vt
d = (20.0 m/s)(12.0 s)
d = 240 m Horizontal Distance Traveled
00
Answer:
10 m/s
Explanation:
Velocity = frequency * wavelength
Velocity = 2.5 * 4
Velocity = 10 m/s
Hole up your right hand like you're holding a glass of water and point with your thumb in the direction the current is travelling through the wire the rest of your fingers indicate the magnetic field lines direction
It is d or c i say c because its mixed with chemicals and d bc the temperture drop to get it cold
