Answer:

Move the small car so it appears on the left side of the lens.

Explanation:

The small car should be moved to the left side of the lens. This is because any image formed by a lens either concave or convex is to placed below the point of intersection of two rays, one of which is the divergence ray that reflect back passing through the focus (2) and the second ray passing through the optical center (1)

A motorcycle traveling at 25 m/s accelerates at a rate of 6 m/s2 for 4 seconds. What is the final speed of the motorcycle in m/s

givi [52]

Initial velocity = Vo= 25 m/s

Final velocity = V = x

Acceleration= a = 6 m/s^2

time= t = 4 seconds

Appy the equation:

V = Vo + at

Replacing:

V = 25 + 6(4) = 25 + 24 = 49 m/s

Bumek [7]

Answer:

Yes, the car has acceleration.

Explanation:

Acceleration is defined as the rate of change of velocity. The velocity is a vector quantity. If a car is moving with constant speed but taking a turn, it means the velocity is changing, so the car have some acceleration.
