The profile of the cables on a suspension bridge may be modeled by a parabola. the central span of a bridge is 12101210 ft long and 128128 ft high. the parabola y equals 0.00035 x squaredy=0.00035x2 gives a good fit to the shape of the cables, where startabsolutevalue x endabsolutevalue less than or equals 605x≤605, and x and y are measured in feet. approximate the length of the cables that stretch between the tops of the two towers.

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

The air that we breath is made mostly of which gaseous molecule
