Given parameters:
Initial velocity of eraser = 5.0m/s
Time = 7.0s
Unknown:
Final velocity = ?
Solution:
Since we have been given the initial velocity and duration of the throw, we can apply the appropriate motion equation to solve this problem.
V = U - 2gt
where V is the final velocity
U is the initial velocity
g is the acceleration due to gravity = 9.8m/s²
t is the time taken
V = U - gt
V = 5 - (9.8)(7)
V = -63.6 or -64m/s
The velocity is -64m/s
Answer:
Yes it is a solid
Explanation:
It just has unusual properties.
Does it float when you drop it? then it is not a gas.
Does it pour into any container as water does? Then it is not a liquid.
So it's a solid.
And it can change it's shape
A). The sun is highest in London, but will not pass the ship
for another 5 hours.
Since the sun moves from east to west, the ship must be
5 hours west of Greenwich.
Each hour of sun motion is 15° of longitude.
The ship's longitude is (5 x 15°) = 75° West.
The ship may be sailing down Columbia Boulevard
in Maple Shade, New Jersey.
B). The latitude at Buffalo's City Hall is 42.887° North.
Polaris is always within about 2/3 of a degree of that angle
above the northern horizon, when viewed from City Hall.
Choice 2) is the most appropriate.
I think <span>its C
hope it helps

just analyze it in this way:
20cos30*=10( radical 3 )
20sin30*=10
