Compare the kinetic energies of a ball moving at 5 m/s to when it is moving

Physics
1 answer:
Fantom [35]3 years ago
5 0

Answer:

B

Explanation:

KE = mv²/2

The more velocity (speed) is, the more kinetic energy an object has.

Because 10 m/s > 5 m/s,  KE at 10 m/s > KE at 5 m/s.

A tangent line drawn on a velocity-time graph has a rise of 19 m/s and a run of 4.0 m/s. How large is the acceleration? What typ
klemol [59]

Answer:

Acceleration = 4.8 m/s²

Explanation:

Given:

Change in velocity = 19 m/s

Change in time = 4 s

Find:

Acceleration

Computation:

Acceleration = Change in velocity / Change in time

Acceleration = 19/4

Acceleration = 4.8 m/s²

Positive acceleration

True or False. The pressure inside a piston is the same in all directions.
Dominik [7]

Answer:

True

Explanation:

Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.
