Answer:
Explanation:
KE = ½mv² = ½(6.8)8² = 217.6 J
round as appropriate because that result is way too much precision for the inputs provided. Arguably should be 200 J based on the single significant digit of the velocity.
–0.05 m/s
Explanation:
The total momentum of the system player+basketball must be conserved before and after the ball has been thrown.
Before throwing the ball, the total momentum of the system is zero, because can assume both the player and the basketball being at rest:
The total momentum after the ball has been thrown is instead the sum of the momenta of the the player and of the basketball:
where
is the player's mass
is the player's velocity
is the ball's mass
is the ball's velocity
For the conservation of momentum, we have
And the negative sign means that the player travels in the opposite direction to the ball.
1)the edges where two plates meet are plate boundaries.
2)a sudden slip on a fault triggers an earthquake as stress in the edge overcomes the tension that releases energy into waves that move through the surface of the earth and cause a shake.
3)motion of the ground, aftershocks, shuddering, trembling, wobbling, crashing, falling, breaking, and more
4) the outer layer of Earth is the crust (lithosphere) which is made up of hot molten rock and granite.
