3 0

Answer:

d = 98.67m

Explanation:

equation:

vf^2 = vi^2 + 2ad

(44m/s)^2 = (0m/s)^2 + 2(9.81m/s^2)(d)

1936m^2/s^2 = 19.62m/s^2(d)

divide both sides by 19.62m/s^2

d = 98.67m approximately

A stuntman is being pulled along a rough road at a constant velocity by a cable attached to a moving truck. The cable is paralle
Alex73 [517]

Answer:

715 N

Explanation:

Since the system is moving at a constant velocity, the net force must be 0. The tension on the road is equal and opposite direction with the kinetic friction force created by the road and the stuntman.

Let g = 9.8 m/s2

Gravity and equalized normal force is:

N = P = mg = 107*9.8 = 1048.6 N

Kinetic friction force and equalized tension force on the rope is

T = F_{\mu} = N\mu = 1048.6 * 0.682 = 715.1452 N

How can wind put off fire?
kipiarov [429]
♥ If the wind is strong enough it can do so.
♥ By having a strong enough wind you can blow out the fire before the flame can consume any more vapor.
♥ If the wind is fast enough, like a birthday cake candle for example, the wind will burn out.
