If a projectile is fired with an initial velocity v0 meters per second at an angle...

If a projectile is fired with an initial velocity v0 meters per second at an angle α above the horizontal and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equations x=(v0 cos α)t & y=(v0 sin α) t-1/2gt2 Suppose α=30o and v0=500 m/s (a) At what time t does the projectile hit the ground? (b) How far does the projectile travel from the time it is fired until the time...

A ten grams ball glides to the left at a speed of 0.4 meters per second...

A ten grams ball glides to the left at a speed of 0.4 meters per second on a frictionless flat surface at the OC fair skating rink. The ball collides head-on, elastically, with another larger ball with mass 30 grams which was gliding to the right with a speed of 0.2 meters per second. A. After the collision, what is the final velocity of each ball. B. What is the change in momentum for each ball? How do they compare...

A hockey puck (1) of mass 130 g is shot west at a speed of 8.40 m/s. It strikes a second puck (2), initially at rest, of mass 124 g. As a result of the collision, the first puck (1) is deflected at an angle of 32° north of west and the second puck (2) moves at an angle of 40° south of west. What is the magnitude of the velocity of puck (1) after the collision?
