Answer:
56.25 m
Explanation:
Cinematics describes the variables involved in movement without dealing with its causes. There are four main concepts in cinematics: Velocity (or its scalar equivalent, the speed), acceleration, time and displacement (or its scalar equivalent, distance).
We know the bobsled starts at 32m/s and ends at 22m/s with acceleration . The acceleration is negative because the bobsled is breaking of losing speed
The formula relating these three variables is
Solving for x
The weight of the mouse in the SI unit would be 0.02 kg.
Mass is the unit which describe the quantity of matter in an object, the SI unit of mass is kilogram.
And conversion factor of one pound to one kg is
1 lb=0.4535 kg
Now the mass of the mouse in Si unit is calculated as
m=0.4535*4.41*10^(-2)
=0.02 kg
Therefore the mass of the mouse in the SI unit is 0.02 kg.
I think its a. i am not sure though.
Answer:
Explanation:
“The Sound of Thunder” is set in the year 2055. Time Safari, Inc. offers time-travel opportunities to hunt and kill exotic and now-extinct animals. In the hunt described in the story, the team of two guides and three hunters goes back to prehistoric days in order to kill the largest dinosaur of them all, a Tyrannosaurus rex. The business has already put safety precautions into place so that these trips can be made without unduly impacting the future. The animals that are killed are ones that have already been identified as doomed. For example, the T rex in question was going to be killed by a falling tree anyway. The safari leaders also built a path for visitors to step on so that no element of the past setting is tampered with. Even the slightest misstep could have implications for the future.
Answer:40kg m/s
