(a) Find the horizontal and vertical components of the initial velocity. v 60 m/s v 30o 0x 0y v0x = 60cos30 = 52 m/s v0y = 60sin30 = 30 m/s
  • The center of the strike zone should be over the middle of the plate and about 33 inches or 2.77 feet above the ground (it depends on the height of the batter, of course). Here's the trajectory of a fastball which ends up in the center of the strike zone, as seen from the third-base side of the field.
  • So in this problem we have a ball that is getting thrown straight up into the air. We know a few things about its voyage. First of all, it travels 16 meters into the air. That's its highest point. Um, at that highest point, it reaches zero meters per second before it starts returning to the earth.
  • The positive root is the one we are interested in, since time t = 0 t = 0 is the time when the ball is released at the top of the building. (The time t = −5.0 s t = −5.0 s represents the fact that a ball thrown upward from the ground would have been in the air for 5.0 s when it passed by the top of the building moving downward at 4.9 m/s.)

  • Its height above the ground is determined by how hot the air inside is and its direction of travel depends on the wind. DIRECT. One of the most difficult parts in every TOELF test is its speaking part.
  • 64 metersIf a ball is thrown horizontally at 20 m/s from the top of a cliff that is 50 meters high, the ball will strike the ground 64 m from the base of the cliff (20m/s x 3.2 s).
  • The ball gains energy of motion, known as kinetic energy. When the ball hits the floor and stops, that energy has to go somewhere. The energy goes into deforming the ball-- from its original round shape to a squashed shape. When the ball deforms, its molecules are stretched apart in some places and squeezed together in others.
  • A ball is thrown straight up from the ground with speed v_0. At the same instant, a second ball is dropped from rest from a height H, directly above the point where the first ball was thrown upward. There is no air resistance. Find the value of H in terms of v_0 and g so that at the instant when the balls collide, the first ball is at the highest point of its motion.
