The magnitude of acceleration is (change in speed) / (time for the change).
Change in speed = (speed at the end) - (speed at the beginning) =
(16 m/s) - (0) = 16 m/s .
Time for the change = 4 s .
Magnitude of acceleration = (16 m/s) / (4 s) = 4 m/s per sec = 4 m/s² .
La longitud del faldón de la rampa es de 5.4 m.
La pendiente expresada en porcentaje sigue la siguiente ecuación:
(1)
Donde:
- y es la elevacion de la rampa (faldón)
- x es la longitud de la ramapa (20 m)
Sabemos que la pendiente es de 27%. Por lo tanto, usando la ecuación 1, despejamos y.
![27=\frac{y}{20}*100](https://tex.z-dn.net/?f=27%3D%5Cfrac%7By%7D%7B20%7D%2A100)
![y=\frac{27*20}{100}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B27%2A20%7D%7B100%7D)
La longitud del faldón es 5.4 m

The acceleration exerted by the object of mass 10 kg is ![\mathbf{1} m / \boldsymbol{s}^{2}](https://tex.z-dn.net/?f=%5Cmathbf%7B1%7D%20m%20%2F%20%5Cboldsymbol%7Bs%7D%5E%7B2%7D)
Answer: Option A
<u>Explanation:</u>
According to Newton’s second law of motion, any external force acting on a body will be directly proportional to the mass of the body as well as acceleration exerted by the body. So, the net external force acting on any object will be equal to the product of mass of the object with acceleration exerted by the object. Thus,
![Force = Mass \times Acceleration](https://tex.z-dn.net/?f=Force%20%3D%20Mass%20%5Ctimes%20Acceleration)
So,
![Acceleration=\frac{\text {Force}}{\text {Mass}}](https://tex.z-dn.net/?f=Acceleration%3D%5Cfrac%7B%5Ctext%20%7BForce%7D%7D%7B%5Ctext%20%7BMass%7D%7D)
As the force acting on the object is stated as 10 N and the mass of the object is given as 10 kg, then the acceleration will be
![Acceleration =\frac{10 \mathrm{N}}{10 \mathrm{kg}}=1 \mathrm{m} / \mathrm{s}^{2}](https://tex.z-dn.net/?f=Acceleration%20%3D%5Cfrac%7B10%20%5Cmathrm%7BN%7D%7D%7B10%20%5Cmathrm%7Bkg%7D%7D%3D1%20%5Cmathrm%7Bm%7D%20%2F%20%5Cmathrm%7Bs%7D%5E%7B2%7D)
So, the acceleration exerted by the object of mass 10 kg is ![\mathbf{1} m / \boldsymbol{s}^{2}](https://tex.z-dn.net/?f=%5Cmathbf%7B1%7D%20m%20%2F%20%5Cboldsymbol%7Bs%7D%5E%7B2%7D)
