Answer:

Explanation:

acceleration = change in speed / change in time

for 1, speed increases over time, so positive acceleration

for 3, speed decreases over time, so negative acceleration (or deceleration)

The answer is B, because 1 is acceleration and 3 is deceleration. 2 and 4 are staying at a constant speed which means it isn’t speeding or slowing but it’s staying the same.

Sergio039 [100]

Answer: it is incorrect because skepticism helps scientists recognize when ideas are not supported by evidence.

Explanation:

Skepticism is simply the understanding that there can be uncertainty when it comes to knowledge in certain areas.

From the question, we are informed that John doesn't think that skepticism should play an important role in the scientific process and that he says that skepticism interferes with scientific consensus.

The statement that best describes John's conclusion is that it is incorrect because skepticism helps scientists recognize when ideas are not supported by evidence.

With "toward the wall" designated as the positive direction, the average acceleration felt the ball in the 0.0158 s of contact with the wall is

$a_{\rm ave} = \dfrac{-26.412\frac{\rm m}{\rm s} - 28.4\frac{\rm m}{\rm s}}{0.0158\,\mathrm s} ≈ \boxed{-3470 \dfrac{\rm m}{\mathrm s^2}}$

A roller coaster has a vertical loop with radius 25.7 m. With what minimum speed should the roller-coaster car be moving at the

gogolik [260]

Answer:

15.88m/s

Explanation:

At the top of the roller coaster you will have three forces acting on the roller-coaster. See the image below. Fc is the centripetal force (for an object in circular motion), Fg is the gravitational force, and Fn is the normal force. To achieve the minimum speed we assume the roller-coaster is barely touching the vertical loop and so the normal force is zero. This leaves two acting forces.

$F_g = F_c\\mg = \frac{m\times v^2}{r}\\v = \sqrt{gr} = \sqrt{9.81 \times 25.7} = 15.88 m/s$
