Answer:
The kinetic energy of the arrow after release is 89.056 J.
Explanation:
Given that,
Mass of arrow, m = 23 g = 0.023 kg
Velocity of the arrow, v = 88 m/s
The power stroke of the bow is 57 cm. The peak draw weight of the bow is 312 N. We need to find the kinetic energy does the arrow have after release. So, it is given by :
So, the kinetic energy of the arrow after release is 89.056 J. Hence, this is the required solution.
Our sun is AVERAGE in every way among the known stars, including mass, age, size, temperature, etc. It doesn't stand out in any way.
Answer:
Direction
Explanation:
Speed is a scalar quantity, that is, it has only magnitude
While velocity is a vector quantity, which has both direction and magnitude.
Velocity is also called speed with direction.
Hence, we need to know the direction in which the car is moving in order to know the velocity.
Answer: It can only match if you make it.
Explanation:
Answer: Efficiency signifies a peak level of performance that uses the least amount of inputs to achieve the highest amount of output.
Explanation: It minimizes the waste of resources such as physical materials, energy, and time while accomplishing the desired output.
