Acceleration, a =  (v - u)/t

where v is the final velocity, u is the initial velocity, and t is the time.

This formula on a velocity time graph represents the slope of the graph.

Answer: Hello there!

in this case, you have a graph of velocity vs time, then in this graph is represented the function v(t).

The acceleration is defined as the integral with respect to the time of the velocity v(t), then we could calculate the mean acceleration between two times in a next way:

a = \frac{v(t2) - v(t1))}{t2 -t1}

this is the slope between the times t2 and t1, where t2>t1 and V(t2) is the velocity at the time t2 (the final velocity) and v(t1) is the velocity at the time t1 (the initial velocity). In this case, a is the mean acceleration between these times.

1. If you push a 40.0kg mass object with a force of 145.ON, what will be the object's
horrorfan [7]

Newton said . . . F = m a

Divide each side by  m . . .  a = F / m

Acceleration = (force) / (mass)

Acceleration = (145.O N) / (40.0 kg)

<em>Acceleration = 3.625 m/s²</em>

a moving electron accelerates at 5200m/s^2 in a 55.0 direction. After 0.350as,it has a velocity of 6598m/s in a -20.5 direction.
Lady bird [3.3K]

Answer:

  -3802 m/s

Explanation:

The y-component of the final velocity is ...

  (6598 m/s)·sin(-20.5°) ≈ -2310.7 m/s

The y-component of the velocity due to acceleration is ...

  (5200 m/s²)(0.350 s)sin(55°) ≈ 1490.9 m/s

Then the initial velocity in the y-direction is found from ...

  initial velocity + change in velocity = final velocity

  initial velocity = (final velocity) - (change in velocity)

  = -2310.7 m/s - 1490.9 m/s ≈ -3802 m/s

In a light interference pattern, alternate dark and bright fringes are seen. Why are the bright fringes formed?
madreJ [45]
The light interference pattern is a series of light and dark stripes.

The bright stripes are areas where there is CONstructive interference.

The dark stripes are areas where there is DEstructive interference.
