a projectile is launched from ground level with an initial speed of 85 meters per second at an angle 40 degrees with respect to horizontal. at the instant two seconds before the striking ground, determine the horizontal and vertical components of the velocity of the projectile
Homework Answers
We know that in projectile motion horizontal component is constant so,
Time of flight is given as:
So the projectile will be at highest point (where vertical velocity is zero) at
As we have to find velocity 2 sec before strike
But we know that from the highest point time taken by projectile to reach ground is
So time during which the vertical velocity will increases from 0 to v is given as:
sec
Therefore,
downward

A projectile is launched from a point on level ground with initial speed 15.9 miles/hour and initial angle of 50.1 degrees. Air resistance may be ignored and normal earth gravity is present. Calculate the magnitude of the final value of the horizontal component of velocity in m/s just prior to the projectile striking the ground. [Note: Don't forget to convert units as needed.]

A projectile of mass M #13.4 kg is launched over level ground at a speed 28.6 and at an angle of 46.5 degrees above the horizontal. At the instant that the projectile is at what would be its highest point it explodes into two pieces; after the explosion there is a piece of mass ml = 5.2kg which has a vertical component of velocity of 9.7 , and a second piece of mass m2 which moves downwards. The explosion does...
