A car goes around a curve of radius 60 m at a constant speed of 15 m/s. Which of the following values is the centripetal acceler

ation of the car?
Physics
1 answer:
IRISSAK [1]3 years ago
4 0

Answer:

3.75 m/s^2

Explanation:

The centripetal acceleration of an object in uniform circular motion is given by the equation:

a=\frac{v^2}{r}

where

v is the tangential speed of the object

r is the radius of the trajectory

In this problem, r = 60 m and v = 15 m/s, therefore the centripetal acceleration of the car is

a=\frac{(15 m/s)^2}{60 m}=3.75 m/s^2

When does PE equal KE?
dybincka [34]
PE equals KE when KE is 50%. 

Like below:

E = PE + KE 
E = 50 + 50 
E = 100.

Remember, both KE and PE always have to add up to 100 so that is why PE is equal to KE when KE is 50% of energy. 

Hope I helped. :)

The slope of this graph is _____.
Artemon [7]

The slope of the illustrated graph would give us the velocity of the object whose motion is plotted in the graph.

<h3>What is velocity?</h3>

Velocity refers to the rate of movement of objects along a particular line. In other words, the velocity of an object is the speed of the object in a specific direction relative to time.

Also, velocity = displacement/time.

In the graph, the slope is given by: Δy/Δx = displacement/time = velocity.
