Explanation:
From the question we are told that
The mass of the pumpkin is
The distance of the the car from the building's base is
The height of the roof is
The height is mathematically represented as
Where g is the acceleration due to gravity which has a value of
substituting values
making the time taken the subject of the formula

Answer:
The kinetic energy of the particle as it moves through point B is 7.9 J.
Explanation:
The kinetic energy of the particle is:
<u>Where</u>:
K: is the kinetic energy
: is the potential energy
q: is the particle's charge = 0.8 mC
ΔV: is the electric potential = 1.5 kV
Now, the kinetic energy of the particle as it moves through point B is:
Therefore, the kinetic energy of the particle as it moves through point B is 7.9 J.
