Answer: Gravity slows the ball down as it goes up and eventually stops it from going up and starts to pull it back down to earth.
Explanation:
Answer: 0
Explanation: Initial velocity is 0.
I think it is B Because it sounds like the best choice
Answer:
The answer is below
Explanation:
Momentum is used to measure the quantity of motion in an object. Momentum is the product of mass and velocity.
Momentum = mass * velocity
The principle of conservation of momentum states that momentum cannot be created or destroyed but can be transferred. Therefore the momentum before and after an action is equal.
Initial momentum = Final momentum
Let m be the mass of the diver, M be the mass of the raft, u be the initial velocity of the diver, U be the initial velocity of the raft, v be the final velocity of the diver and V be the final velocity of the raft.
m = 71 kg, M = 500 kg, v = 6 m/s
Initial both the raft and diver are at rest, hence u and U is zero, hence:
mu + MU = mv + MV
71(0) + 500(0) = 71(6) + 500(V)
0 = 426 + 500(V)
500(V) = -426
V = -426/500
V = -0.852 m/s
Answer:
A., the variables have a direct relationship.
Explanation:
As K rises, L rises.
It's not B. because one isn't rising as the other is lowering.
It's not C. because undefined would be a vertical line.
