Solution :
Energy of photon, E = 6.7 eV
E = joule
Kinetic energy,
Kinetic energy at high speeds
r - 1 = 7130
r = 7130 + 1
r = 7131
Δ = 1 - 0.99999999017
= 0.00000000933
Relative mass,
kg
By definition, speed is the integral of acceleration with respect to time.
We have then:
As the acceleration is constant, then integrating we have:
Where,
vo: constant of integration that corresponds to the initial velocity
We observe then that the speed varies linearly when the acceleration is constant .
Therefore, for constant acceleration, the velocity is changing.
Answer:
an object with a constant acceleration always have:
A. changing velocity
