a motorcycle is capable of accelerating at 5.1 m/s starting from rest how far can it travell in 1.5 sec
Katarina [22]
The answer is 21m because the motion is in one dimension with constant acceleration.

The initial velocity is 0, because it started from rest, the acceleration <span>ax</span> is <span>4.7<span>m<span>s2</span></span></span>, and the time t is <span>3.0s</span>

Plugging in our known values, we have

<span>Δx=<span>(0)</span><span>(3.0s)</span>+<span>12</span><span>(4.7<span>m<span>s2</span></span>)</span><span><span>(3.0s)</span>2</span>=<span>21<span>m</span></span></span>

marusya05 [52]

If you want to maximize your potential energy, you can move the cart in any direction and get the same outcome because the distance it travels in each direction is equal.

The energy that a body possesses in its resting state is called its potential energy. The energy of a moving object is known as its kinetic energy. Stored energy that is conditional on the spatial orientation of the system's components; is also known as potential energy.

When a spring is either squeezed or stretched, the resulting increase in potential energy can be used to do work. Potentially, a steel ball has more energy in the air than it does when it hits the ground.

Here, we can observe that the carts are shifted to the right or left by one space. Consequently, the potential energy will also change in response to the motions.

To see a similar example:

The right question is:

Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts to one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?

a. Moving the cart on Track 1 one space to the right (→).

b. Moving the cart on Track 2 one space to the left (←).

c. Moving the cart on Track 2 one space to the right (→).

d. All these movements will result in the same change in potential energy because they each move a cart the same distance.

In a carnival ride, passengers stand with their backs against the wall of a cylinder. The cylinder is set into rotation and the
klio [65]

Answer:

8.2 m/s

Explanation:

radius (r) = 1.3 m

coefficient of friction (u) = 0.19

acceleration due to gravity (g) = 9.8 m/s^{2}

for the passengers to remain stuck on the wall, the normal force must be equal to the centripetal force (while considering the coefficient of friction).

normal force = centripetal force x coefficient of friction

mg = \frac{mv^{2} }{r} x u

g =  \frac{v^{2} }{r} x u

v = \sqrt{\frac{gXr}{u} }

v = \sqrt{\frac{9.8x1.3}{0.19} }

v = 8.2 m/s

the minimum speed the passengers can have to stick to the wall = 8.2 m/s
