Answer: 896J
Explanation:
Given that
Mass of motorcycle = 112kg
kinetic energy = ?
velocity of the motorcycle = 4m/s
Since kinetic energy is the energy possessed by a moving object, and it depends on the mass (m) of the object and the velocity (v) by which it moves. Therefore, the motorcycle has kinetic energy
i.e K.E = 1/2mv^2
KE = 1/2 x 112kg x (4m/s)^2
KE = 0.5 x 112 x 16
KE = 896J
Thus, the motorcycle has 896 joules of kinetic energy.
Answer:
a.Velocity of A and Velocity of B will be opposite in direction.
b.Both velocities have the same direction.
c. The two objects will move in a direction of some angle α.
Explanation:
When the angle gets maximum the velocities of the two objects pull each other and move in opposite direction. But when the two objects make an angle zero degree with each other their motion is in the same direction.
Column A: x-axis, input, domain
Column B: y-axis, output, range
Those are other ways to describe them
hope i helped:)
