Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...

If a projectile is fired with an initial velocity of 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 equationsx=(v0 cos α) t y=(v0 sin α) t-1/2 g t2where g is the acceleration due to gravity (9.8 m / s2)(a) If a projectile is fired with α=45° and v0=900 m / s, when will it hit the ground? How...

OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...
