A ball starts from rest and accelerates at 0.460 m/s2 while moving down an inclined plane 8.85 m long. When it reaches the botto

Ivahew [28]

Answer:

$V=2.8534m/s \approx 3m/s$

Explanation:

From the question we are told that

Acceleration $a=0.460m/s$

Distance traveled $S_1=8.5m$

Distance traveled $S_2=15.6m$

Generally the velocity of the ball at the bottom of the first plane V is mathematically given by

$v^2=2as$

$v=\sqrt{2as}$

$V=\sqrt{2*0.460*8.85}$

$V=2.8534m/s \approx 3m/s$

Cloud [144]

The <u>apparent magnitude</u> of a star refers to its brightness as seen from your eyes and <u>absolute magnitude</u> being the actual brightness of a star.

<h3>What is magnitude?</h3>

Magnitude can be defined as a unitless measure which is used to show the brightness of an object in comparison with the brightness of another object.

Basically, there are two types of magnitude and these include the following:

Apparent magnitude

Absolute magnitude

In conclusion, the <u>apparent magnitude</u> of a star refers to its brightness as seen from your eyes and <u>absolute magnitude</u> being the actual brightness of a star.

A crane does 9,500 J of work to lift a crate straight up using a force of 125 N. How high does the crane lift the crate? 0. 013

Maurinko [17]

The distance covered as the crane does work is 76 m.

Recall that the work done in lifting the crane is the product of force and distance covered. In this case, we are talking about the distance through which the crane is raised. Therefore;

Work done = Fs

F = Force applied

s = Distance covered

Substituting values;

Work done/Force applied = Distance covered

Distance covered = 9,500 J/125 N

Distance covered = 76 m
