In fighting forest fires, airplanes work in support of ground crewsby dropping water on the fires. a pilot is practicing by dropping acanister of red dye, hoping to hit a target on the ground below. ifthe plane is flying in a horizontal path 90.0 m above the ground and with a speed of69.0 m/s (153 mi/h), at what horizontal distance from thetarget should the pilot release the canister?

The ballistic pendulum was invented in 1742 by english mathematician benjamin robins. it consists of an initially stationary pendulum that moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. the known variables are the bullet's mass m, the pendulum's mass m, and the height to which the block and bullet swing, determined by the length of the pendulum l and final angle θ. two principles of physics are necessary to solve for the bullet's original velocity. what are these principles? conservation of momentum and newton's third law conservation of energy and conservation of angular momentum grade summary deductions 0% potential 100% conservation of momentum and newton's second law. newton's second law and conservation of angular momentum. conservation of energy and newton's third law conservation of momentum and conservation of angular momentum. conservation of momentum and conservation of energy conservation of energy and newton's second law.

A20 cm long spring is attached to a wall. the spring stretches to a length of 22 cm when you pull on it with a force of 100 n. what is the spring constant

Distinguish between linear momentum and angular momentum
