Answer:
a = 3 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 60 [m/s]
Vo = initial velocity = 20 [m/s]
a = acceleration [m/s²]
t = time = 10 [s]
Now replacing these values we have:
60 = 20 + (a*10)
60 - 20 = 10*a
30 = 10*a
a = 3 [m/s²]
The electric field generated by a proton is a radial field, so we would see the field lines going radially from the proton toward every direction. I've attached a picture representing the electric field generated by a positive charge, such as a proton, and we can see the field lines going radially from the charge toward every direction.
The kinetic energy of an object of mass m moving with speed v is given by:
For the bicycle in our problem,
and 
, so the kinetic energy is
