Answer:

Explanation:
Given that:
Height of jump, 
length of elastic cord, 
spring constant of the cord, 
mass of the body that jumps, 
Force on the bungee elastic cord:


Now this force F will be responsible for the elongation in the elastic cord, so:
............................(1)
where :
k = spring constant
x = extension in the elastic cord
using eq. (1)


So the cord stretches 19.6 meters more beyond its original length of 30 meters.
Hence, the remaining distance from the river surface at the bottom is:


The coefficient of kinetic friction between the baserunner and the ground is 0.51.
<h3>
Coefficient of kinetic friction </h3>
The coefficient of kinetic friction between the base runner and the ground is calculated as follows;
μ = a/g
where;
- a is acceleration
- g is gravity
v² = u² + 2as
a = (v² - u²)/(2s)
a = (8.451² - 2.322²)/(2 x 6.596)
a = 5 m/s²
μ = 5/9.8
μ = 0.51
Thus, the coefficient of kinetic friction between the baserunner and the ground is 0.51.

Answer:
The magnitude of change in momentum of the ball is
and impulse is also
Explanation:
Given:
Velocity of a pitched ball

Velocity of ball after impact

From the formula of change in momentum,

Here mass is not given in question,
Mass of ball is 
Change in momentum is given by,


Magnitude of change in momentum is

And impulse is given by


So impulse and
Therefore, the magnitude of change in momentum of the ball is
and impulse is also
