Exactly 3.0 s after a projectile is fired into the air from the ground,it is observed to have a velocity v=(8.6i+4.8j) m/s,where the x axis in horizontal and the y axis is positive upward.Determine (a) the horizontal range of the projectile,(b) its maximum height above the ground...
A ball is thrown vertically upward with a speed of 17 m/s. How long does the ball take to hit the ground after it reaches its highest point? Free-Fall When objects are only under the influence of gravity, they are said t...
A projectile is fired from a gun and has initial horizontal and vertical components of its velocity equal to Calculate the initial and final speed with which a bullet was fired vertically upwards and the height which it has reached if it returned to the ground aft...

A bullet is fired at an angle of 45^o. Neglecting air resistance, what is the direction of acceleration during the flight of the bullet? a) upward b) downward c) depending on the initial velocity d) at a 45^o ...
Answer to: A 10 \ kg gun recoils with a speed of 0.1 meter per second as it fires a 0.001 \ kg bullet. What is the speed of the bullet as it...
What range will a projectile reach if it is launched horizontally at 4.21 m/s from a height of 0.996 m? When an object is thrown upward, how much speed does it lose each second (ignoring air resistance)? A bullet is fired at ...
A bullet is fired vertically downward from a stationary helicopter. The helicopter is 800 m above the ground, and the bullet has an initial speed of 600 m/s. Just before the bullet hits the ground below, what is its final speed...
From the moment a projectile is launched, it begins its acceleration toward the Earth. While there are various techniques that can be used to keep a projectile on target, it is generally accepted that the further you are from a target, the higher you have to launch a pr...
