A converging lens can produce both real and virtual images depending on the position of the object. Explain when converging lens
es can produce virtual images and describe the image produced.
A) A virtual image is produced if the object is on the focal point, the image is upright, enlarged and on the same side of the lens as the object.
B) A virtual image is produced if the object is on the focal point, the image is inverted, enlarged and on the opposite side of the lens from the object.
C) A virtual image is produced if the object is between the focal point and the lens, the image will be upright, enlarged and on the same side of the lens
as the object.
D) A virtual image is produced if the object is between the focal point and the
lens, the image will be upright, reduced and on the opposite side of the
lens from the object.

Explanation:
It is given that,
Total mass is 70 kg
The truck exerts a constant force of 20 N.
Then the net force is given by :
F = ma
a is acceleration of rider
Initial velocity of rider is 0. So, using equation of kinematics to find the final velocity as :
Since, 1 m/s = 2.23 mph
4.28 m/s = 9.57 mph
So, the speed of the rider is 4.28 m/s or 9.57 mph.
