Answer:
Velocity ratio in pulley is defined as the ratio of distance travelled by load and effort in the same time interval.
Answer:
speed = wavelength * frequency
Explanation:
Thenks and mark me brainliest :)
Slow down before entering the curve. Stay close to the outside. Use the gas pedal as you enter the middle of the curve.
Answer:
Explanation:
Given parameters:
Average speed = 3.5miles per second
Unknown:
Initial speed = ?
Average speed = ?
Final speed in the interval = ?
Solution:
Since the bicyclist started from rest and speeds up steadily, it is correct to assume that her starting or initial speed is 0m/s.
At a state of rest, a body has no speed.
Average speed is the sum total of the speed covered at each time interval. This value is given already to be 3.5miles per second.
Final speed is the speed before the bicycle halts. This speed will be the same as the average speed here which is 3.5miles per second.
Speed is the rate of change of distance with time.
