The record distance in the sport of throwing cowpats is 81.1 m. this record toss was set by steve urner of the united states in 1981. assuming the initial launch angle was 45° and neglecting air resistance, answer the following. (a) determine the initial speed of the projectile. m/s

28.2 m/s

Explanation:

The range of a projectile launched from the ground is given by:

where

v is the initial speed

g = 9.8 m/s^2 is the acceleration of gravity

is the angle at which the projectile is thrown

In this problem we have

d = 81.1 m is the range

is the angle

Solving for v, we find the speed of the projectile:

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
