A bowling ball is on the end of a rope of length 5 meters, the other end of which is attached to a hook in the ceiling. The ball

Answer:

$a = 0\,\frac{m}{s^{2}}$

Explanation:

Let consider the following system, which is described in the image attached below and two reference axis, one parallel and the other perpendicular to the direction of motion. The corresponding equations of equilibrium are described herein:

$\Sigma F_{n} = T - m\cdot g \cdot \cos \theta = 0$

$\Sigma F_{t} = m\cdot g \cdot \sin \theta = m\cdot a$

The acceleration of the bowling ball at the lowest point occurs at $\theta = 0^{\textdegree}$

$m\cdot g \cdot \sin \theta = m\cdot a$

$g\cdot \sin \theta = a$

$a = 0\,\frac{m}{s^{2}}$

Assume theres no air reaistance. (or else the ball will oppose the motion of the ball, hence decrease the velocity increase)
see if there are any problems!

If I want to calculate the normal force of an object on two legs but the weight of the object is not uniform throughout, how do

RoseWind [281]

Use the right equation. To calculate the normal force of an object at an angle, you need to use the formula: N = m * g * cos (x) For this equation, N refers to the normal force, m refers to the object's mass, g refers to the acceleration of gravity, and x refers to the angle of incline.

What does it mean to have an acceleration of -10 m/s^2 when the velocity is 80 m/s?

mamaluj [8]

Answer:

1,3

Explanation:

As the acceleration is -10m/s^2 , that means deceleration is occurring. That means, the object is slowing down.

v=u-at

or, 0=80-10t

or, t=8 seconds

So, the object will stop in 8 seconds.

So, the correct answers are 1 and 3.

Hope, this helps you.
