Explanation:
The lens equation shows the relation among focal length of the lens, image distance and object distance. It can be expressed as:
=
+
where: f is the focal length of the lens, is the object distance to the lens and
is the image distance to the lens.
The lens equation can be used to determine the unknown value among the variables f , and
.
Explanation:
It is given that,
Mass of the tackler, m₁ = 120 kg
Velocity of tackler, u₁ = 3 m/s
Mass, m₂ = 91 kg
Velocity, u₂ = -7.5 m/s
We need to find the mutual velocity immediately the collision. It is the case of inelastic collision such that,
v = -1.5 m/s
Hence, their mutual velocity after the collision is 1.5 m/s and it is moving in the same direction as the halfback was moving initially. Hence, this is the required solution.
