V = dx/dt = (-33/15)t^2 + 3.1
When v = 0 we need to find t => (33/15)t^2 = 3.1 => t = 1.19
a = dv/dt = (-66/15)t At t = 1.19, a = - 5.23
Answer:
The amount of water it displaces (shaded area ) weighs as much as the ship. The weight of the ship pulling down and the upthrust pushing up are equal and opposite forcers so the ship floats.
Explanation:
Now the weight of the ship is more than the maximum possible upthrust so it sinks to the buttom
Answer:
Star, hydrogen and energy
Explanation:
A star is a large ball of gas that generates its own energy by fusing hydrogen atoms to make helium. It is held together by its own gravity. This process emits a tremendous amount of energy, and some of the energy is in the form of light.
The energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. When the core is hot enough, nuclear fusion commences. Fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
I don't know I guess its the plate tectonics
Explanation:
Given that,
Mass of the baseball, m = 0.147 kg
The initial speed of the baseball, u = 42 m/s
The final speed of the baseball, v = -54 m/s (in opposite direction)
We need to find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat. The change in momentum is given by :
We know that the impulse applied to it by the bat is equal to the change in momentum. So, the impulse is 1.764 kg-m/s.
