Explanation:
Let u is the initial speed of the bike. Finally, the bike stops, v = 0
Deceleration of the bike,
Time, t = 5
Distance covered, s = 62.5 m
We need to find the initial speed of the bike. Using third equation of motion as :
u = 11.18 m/s
So, the initial speed of the bike is 11.18 m/s. Hence, this is the required solution.
the nucleus had a positive charge and is surrounded by negatively charged electrons.
