Answer:
Explanation:
When the suitcase is being released, it has a horizontal velocity of v0, a vertical velocity of 0 and vertical acceleration of g
The time it takes for it to drop by the vertical distance of α under acceleration g can be solved using the following equation of motion
This is also the time it takes for the suitcase to travel horizontally at the rate of v0. So the horizontal distance it travels is
Answer:
Explanation:
From the question we are told that:
Mass
Initial Velocity
Final Velocity
Generally the equation for Work-done is mathematically given by
W=\triangle K.E
Therefore
If an has more positive charges than negative charges then It will overall be A.Positive
Answer:
54 J
Explanation:
Kinetic energy is:
KE = 1/2 mv²
where m is mass and v is velocity.
Given m = 3 kg and v = 6 m/s:
KE = 1/2 (3 kg) (6 m/s)²
KE = 54 J
