A Projectile Is Fired from Point 0 at the Edge

question 88

Short Answer

A projectile is fired from point 0 at the edge of a cliff,with initial velocity components of v_0x= 60 m/s and v_0y = 175 m/s,as shown in the figure.The projectile rises and then falls into the sea at point P.The time of flight of the projectile is 40.0 s,and it experiences no appreciable air resistance in flight.What is the magnitude of the velocity of the projectile 21.0 s after it is fired?

Definitions:

Hypertonic

A solution that has a higher solute concentration than the cytoplasm of a cell, causing cell shrinkage.

Hypotonic

Describes a solution that has a lower concentration of solutes relative to the inside of a cell, causing water to enter the cell by osmosis.

Hypertonic

Describing a solution that has a higher concentration of solutes compared to another solution, potentially causing cells to shrink due to water loss.

Solute Concentration

The amount of solute per unit volume of solution, indicating how much of a substance is dissolved in another substance.
