Answer:
312.5 ft
Explanation:
x = xo + vo t + 1/2 a t^2 xo = 0 v0 = 0
x = 1/2 a t^2 = 1/2 (25)(5^2) = 312.5 ft
Answer:
Frequency.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.
Mathematically, the speed of a sound is given by the formula:
Speed = wavelength * frequency
The pitch of a sound you hear depends on the frequency of the sound wave.
Answer:
Explanation:
Sum moments about the rear tires to zero to find the force on the front tires
F[3.13] - 1540(9.81)[3.13 - 1.09] = 0
F = 9,846
so each front wheel supports half of that weight
F/2 = 9846/2 = 4,923 ≈ 4920 N
Sum vertical forces to zero
9,846 + R - 1540(9.81) = 0
R = 5,261
so each rear wheel supports half of that weight
R/2 = 5261/2 = 2630.52 ≈ 2630 N
