Answer:
KE = 1/2mv^2
KE = 1/2(24)(3^2)
KE = 12(9)
KE = 108 J
Let me know if this helps!
B) Moving with zero acceleration.
Explanation:
Acceleration is defined as the rate of change of the velocity per unit time:
![a=\frac{\Delta v}{\Delta t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B%5CDelta%20v%7D%7B%5CDelta%20t%7D)
In a velocity-time graph, this ratio corresponds to the slope of the curve. In fact:
(change in velocity) corresponds to the increase in the y-axis
(change in time) corresponds to the increase in the x-axis
So, acceleration corresponds to the slope of the curve in a velocity-time graph. For cart C, the slope is zero, therefore the acceleration is also zero.
Answer:
u would use the formula for electrostatic force of attraction which is
F = q1q2 / 4pie r^2
Explanation:
i think it would 47 and 47 =2209 ,divide by (4 × pie × 8.98755 × (1.8 ×(10 ^3) )^2)
Answer:c
Explanation:
When an object is performing simple harmonic motion then time period is given by measuring the time period take by object to return its initial position.
Thus we can say that it also valid for maximum position thus period is the correct is answer for this problem.
Time Period of oscillation for spring mass system is
