What does the SLOPE of a Velocity-Time graph represent? * 1 point

Physics
1 answer:
lyudmila [28]3 years ago
6 0

Acceleration

Explanation:

  • In the Velocity-Time graph Velocity is taken in Y-Axis and plotted against Time in X-Axis.
  • The unit of velocity is mentioned in m/s and unit of time is mentioned in seconds.
  • Here we can analyze the instantaneous acceleration and displacement covered.
  • From the slope we can get the body accelerated.
  • From the area under the graph we can get the displacement traveled.
  • We can calculate both average and Instantaneous acceleration from the slope of this graph.

If at 10m above the ground an object has 50J of Kinetic Energy, with 50J of Potential Energy. How high can the object travel?
steposvetlana [31]

Hi there!

\large\boxed{\text{B) 20 meters}}

We know that:

E_T = U + K

U = Potential Energy (J)

K = Kinetic Energy (J)

E = Total Energy (J)

At 10m, the total amount of energy is equivalent to:

U + K = 50 + 50 = 100 J

To find the highest point the object can travel, K = 0 J and U is at a maximum of 100 J, so:

100J = mgh

We know at 10m U = 50J, so we can solve for mass. Let g = 10 m/s².

50J = 10(10)m

m = 1/2 kg

Now, solve for height given that E = 100 J:

100J = 1/2(10)h

100J = 5h

<u>h = 20 meters</u>
