How long would it take to fall 6000 ft?
Well, roughly, it depends on weight, but not at first. Initially you fall at the acceleration of gravity at 32 feet per second per second. Velocity is acceleration x time and you reach a terminal velocity of about 110 mph depending on weight, or about 160 feet per second. Thus it takes 160/32= 5 seconds to reach that speed; then the sped is constant due to (drag) at 160 feet per second. You would have traveled s = 1/2 accel x time squared = 32/2 x 5x5 = 400 feet. You have 5600 feet to go and s = vt = 5600; t = 5600/160 = 35 seconds. Total time is 35 + 5 = 40 seconds
What is the velocity of a five kilogram rock when it strikes the surface of the moon after falling thirty-five feet?
distance = 1/2 gt^2 wher g is acceleration of gravity on moon = about 5 ft/sec/sec 35 = 2.5t^2 t^2 = 14 t = 3.74 seconds velocity = at = 5 x 3.74 = 18.7 feet/second the mass of the rock does not enter into this
What is the angular velocity of a 6 and ndashfoot pendulum that takes 3 seconds to complete an arc of 14.13 feet Use 3.14 for and pi.?
The whole point of a pendulum is that is swings back and forth. It does not travel at constant angular velocity: the angular velocity is zero at the two ends of its arc and it reaches a maximum when the pendulum is vertical. Consequently there cannot be a sensible answer to the question as asked.The average angular velocity, which is an entirely different measure, is 45 degrees per second.
How do you convert 300 feet per 2.92 seconds into miles per hour?
300 feet per 2.92 seconds = ~70.05 (70.0498132) mph
Runner ran 315 feet in nine seconds what is the average speed in feet per seconds?
Divide 315 by 9. 315 / 9 = 35 fps
