During which time interval was the motion fastest?
2 answers:
Answer:
D.4 h to 5 h
Explanation:
The velocity of an object is defined as
where
d is the displacement
t is the time
In a displacement-time graph, such as the one in the figure, the velocity of the object corresponds to the slope of the curve. We see that in this graph, the part where the slope is steeper is between 4h and 5h, so this is the moment where the object is moving faster.

Answer:
The acceleration of proton is 5.56 x 10^10 m/s^2 .
Explanation:
initial velocity, u = 0
Electric field, E = 580 N/C
final speed, v = 10^6 m/s
(a) Let the acceleration is a.
According to the Newton's second law
F = m a = q E
where, q is the charge of proton and m is the mass.
