Answer:
486,750 kg*m/s
Explanation:
Momentum is mass*velocity
M = m*v
M = 8850kg*55m/s
M = 486,750 kg*m/s
Answer:
4.02 s
Explanation:
From the question given above, the following data were obtained:
Angle of projection (θ) = 35°
Initial velocity (u) = 50 m/s
Acceleration due to gravity (g) = 10 m/s²
Time of flight (T) =?
The time of flight of the arrow can be obtained as follow:
T = 2uSineθ / g
T = 2 × 35 × Sine 35 / 10
T = 70 × 0.5736 / 10
T = 7 × 0.5736
T = 4.02 s
Therefore, the time taken for the arrow to return is 4.02 s
Answer:
Try to Rest.
Have a heating pad on the area where it aches.
Relax.
Or take pain pill and wait for it to settle in.
Explanation:
When the average kinetic energy of the particles in the object increases, we sense and measure that change as an increase in the object's temperature.
Answer:
Both of them are Θ(nlgn).
Explanation:
If the array is sorted in increasing order, the algorithm will need to convert it to a heep that will take O(n). Afterwards, however, there are n−1 calls to MAX-HEAPIFY and each one will perform the full lgk operations. Since:
∑i=1n−1lgk=lg((n−1)!)=Θ(nlgn)
Same goes for decreasing order. BUILD-MAX-HEAP will be faster (by a constant factor), but the computation time will be dominated by the loop in HEAPSORT, which is Θ(nlgn).
