The change in temperature is simply 50 / (9/5) = 27.777. We just throw out the 32 from the formula
Exothermic is the right kind of reaction.
Answer:
2 m/s²
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 0 m/s
Final velocity (v) = 12 m/s
Time (t) = 6 s
Acceleration (a) =?
The acceleration of the player can be obtained as follow:
v = u + at
12 = 0 + (a × 6)
12 = 6a
Divide both side by 6
a = 12 / 6
a = 2 m/s²
Thus, the acceleration of the player is 2 m/s²
Answer:
Explanation:
Recall the formula for linear momentum (p):
which in our case equals 26.4 kg m/s
and notice that the kinetic energy can be written in terms of the linear momentum (p) as shown below:
Then, we can solve for the mass (m) given the information we have on the kinetic energy and momentum of the particle:
Now by knowing the particle's mass, we use the momentum formula to find its speed:
No. It has no acceleration, which just means that the forces acting on it are equal and opposite, not that there are no forces exerted on it.
But if you're talking about the resulting Net Force, then yes you can conclude there is no Net Force acting on an object with no acceleration.
