Answer:
The initial speed of the ball was 26.2 m/s
Explanation:
When the football player is in the air at his maximum height the vertical component of velocity is zero, To obtain the horizontal velocity when the player catches the ball we need to apply the linear momentum conservation theorem:
we need to obtain the time taken to go down.
We have a horizontal displacement and the time taken to stop, so:
so:
Answer:
B. does it transfer energy
A wave is a disturbance in a medium. Particles vibrate and TRANSFER their ENERGY to their neighbors.
A freight car of mass 20,000 kg moves along a frictionless level railroad track ... After the push the skateboarder II moves with a velocity of 2 m/s to ... After the collision the cars stick to each other and ... diver jumps with a velocity of 3 m/s in opposite ... A 10 kg object moves at a constant velocity 2 m/s to the right and collides
Current flow depends on other things in addition to the circuit configuration.
If the SAME voltage is applied to some arrangement of the SAME components, the greatest current will occur when they are all in parallel.
