Answer:
Kindly find the graphs attached
Explanation:
For figure 1: There is a steady increase in the position of the object as time increases. This is because despite the negative acceleration (deceleration), the object continues to move and cover more ground as time goes by.
<em>The straight line graph is observed because the acceleration is constant and not varying.</em>
For Figure 2: The graph of velocity vs time will have an inverted nature. This is because since the object is decelerating, it is reducing in its velocity as time goes by (increases). <em>This is also in a straight line since the deceleration is constant.</em>
Answer:
it makes the object speed increase, decrease and change the direction of the object.
Hope it helps!
Answer:90N
Explanation:
Mass=30kg
Centripetal acceleration=3m/s^2
centripetal force=mass x centripetal acceleration
Centripetal force=30 x 3
Centripetal force =90
Centripetal force =90N
The y-component of the acceleration is ![0.28 m/s^2](https://tex.z-dn.net/?f=0.28%20m%2Fs%5E2)
Explanation:
The y-component of the ice skater acceleration can be calculated with the equation
![a_y = \frac{v_y-u_y}{t}](https://tex.z-dn.net/?f=a_y%20%3D%20%5Cfrac%7Bv_y-u_y%7D%7Bt%7D)
where
is the y-component of the final velocity
is the y-component of the initial velocity
t is the time elapsed
Here we have:
- Initial velocity is
at
, so its y-component is ![u_y = u sin \theta_1 = (2.25)(sin 50.0^{\circ})=1.72 m/s](https://tex.z-dn.net/?f=u_y%20%3D%20u%20sin%20%5Ctheta_1%20%3D%20%282.25%29%28sin%2050.0%5E%7B%5Ccirc%7D%29%3D1.72%20m%2Fs)
- Final velocity is
at
, so its y-component is ![v_y = v sin \theta_2 = (4.65)(sin 120.0^{\circ})=4.03 m/s](https://tex.z-dn.net/?f=v_y%20%3D%20v%20sin%20%5Ctheta_2%20%3D%20%284.65%29%28sin%20120.0%5E%7B%5Ccirc%7D%29%3D4.03%20m%2Fs)
The time elapsed is
t = 8.33 s
Therefore, the y-component of the acceleration is
![a_y = \frac{4.03-1.72}{8.33}=0.28 m/s^2](https://tex.z-dn.net/?f=a_y%20%3D%20%5Cfrac%7B4.03-1.72%7D%7B8.33%7D%3D0.28%20m%2Fs%5E2)
