Answer:
A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.
Answer: 3200 joules.
Explanation:
Mass of deer = 100kg
Speed of running deer = 8 m/s
Kinetic energy = ?
Kinetic energy is the energy possessed by a moving body (deer). It is measured in joules.
Thus, Kinetic energy = 1/2 x (Mass x velocity^2)
K.E = 1/2 x (100kg x (8m/s)^2)
K.E = 1/2 x (100 x 64)
= 0.5 x 6400
= 3200 joules
Thus, the kinetic energy of the running deer is 3200 joules.
To solve this problem , we will use the length contraction equation as follows:
L = L0((1 - v^2/c^2))^0.5
where:
L is the desired length
L0 is the length measured at initial frame = 1 m
v is the velocity
c is the speed of light
Substituting by these givens in the above equation, we can calculate L as follows:
L = 1((1 - (0.8 c)^2/c2))^0.5 = 0.6 meters
