Answer:
Explanation:
ASSUMING the defender at 5 m is NOT the goalie.
the ball horizontal velocity is 5 m/0.5 s = 10 m/s
The goalie, presumably at the goal line, has 15 m / 10 m/s = 1.5 s to react and move to the ball position.
Must be little league soccer as 10 m/s is a rather wimpy soccer ball speed.
If a substance absorbs energy but its temperature does not change, then the internal potential energy is changing.
Answer:
A rock dropped from the ceiling of a truck's cargo bay, with the truck moving at constant velocity, the rock strikes the floor exactly below the midpoint of the ceiling.
Explanation:
An object moving at a constant velocity, is changing its displacement at an equal time.That is, the object is moving on a straight line at a constant speed.
Also an object with a constant velocity is not accelerating, since acceleration is the change in velocity with respect to time.
Therefore, A rock dropped from the ceiling of a truck's cargo bay, with the truck moving at constant velocity, the rock strikes the floor exactly below the midpoint of the ceiling.
Answer:
30%
Explanation:
Total profit=$25000
Initial investment=$10000
Return on investment is given by
RoI=(Gain from investment-cost of investment)/cost of investment
RoI=150% but since it's over 5 years, we distribute for 5 years hence annual
Therefore, RoI=30%
