Initial velocity of kangaroo in upward direction (u) = 5.77
Final velocity at the highest point of the journey (v) = 0
Let the maximum height reached be H.
Acceleration due to gravity = -9.8
Now, using the third equation of motion:
H = 1.698 m
The maximum height reached by kangaroo is 1.7 m.
The momentum of a 5kg object that has a velocity of 1.2m/s is 6.0kgm/s.
<h3> MOMENTUM:</h3>
Momentum of a substance is the product of its mass and velocity. That is;
Momentum (p) = mass (m) × velocity (v)
According to this question, an object has a mass of 5kg and velocity of 1.2m/s. The momentum is calculated thus:
Momentum = 5kg × 1.2m/s
Momentum = 6kgm/s.
Therefore, the momentum of a 5kg object that has a velocity of 1.2m/s is 6.0kgm/s.

Answer:
D. The friction force increases by 9600 N.
Explanation:
Frictional force is directly proportional to kinetic coefient of friction.
