Answer:
11.25m
Explanation:
Given parameters:
Initial velocity = 0m/s
Time of running = 3s
Acceleration = 2.5m/s²
Unknown:
Displacement = ?
Solution:
To solve this problem, we apply one of the motion equations.
S = ut + at²
u is the initial velocity
t is the time taken
a is the acceleration
S = (0 x 3) + ( x 2.5 x 3²) = 11.25m
Answer:
Decelerating
Explanation:
One arrow is moving it forward but the other arrow is using more force to move it backwards causing it to have a reduction in speed.
Answer:
Q=22.6L/s
Explanation:
First you must consider the continuity equation at points 1 and 2, which indicates that both flows are of equal value, in this way you get an equation between the two flow rates.
Then you raise the Bernoulli equation taking into account that the height is the same, which makes the term h1-h2 zero.
Using the equations above to calculate one of the speeds.
Finally you find the flow by multiplying the speed by the area.

Answer:
Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few 'magnetic' metals and not all matter.
