<u>Answer:</u>
The ball is rolling at a speed of 0.02 meter per second.
<u>Step by step explanation:</u>
We are given that there is a 800 gram bowling ball rolling in a straight line. If its momentum is given to be 16 kg.m/sec, we are to find its velocity.
For this, we will use the formula of momentum.
<em>Momentum = mass × velocity</em>
16 = 800 × velocity
Velocity = 16/800 = 0.02 meter per second

The density of olive oil is 0.911 g/cm^3 and the density of water is 1.000 g/cm^3.
To calculate the pressure of 1 cm of water,
1000 kg/m^3 * 9.8 m/s^2 * 0.01 m = 98.000 Pa
To calculate the pressure of 1 cm of olive oil
911 kg/m^3 * 9.8 m/s^2 * 0.01 m = 89.278 Pa
Now to calculate the pressure at the bottom of the container, simply add the products of how many cm of each fluid you have. So
21 * 98.000 Pa + 11 * 89.278 Pa = 2058 Pa + 982.058 Pa = 3040.058 Pa
So the pressure at the bottom of the container will be 3040. Pascals.</span>

Answer:
The time taken to get the shuttle is 6.91 minutes.
Explanation:
Given that.
Mass of an astronaut, 
Distance between astronaut and shuttle, d = 48.1 m
Mass of the camera, 
Speed of camera, v = 12 m/s
We need to find the time taken by the astronaut to reach her shuttle. Both shuttle and astronaut are at rest, their initial velocities will be equal to 0. Using the conservation of linear momentum as :
The time taken to get the shuttle is given by :
or
t = 6.91 minutes
So, the time taken to get the shuttle is 6.91 minutes.
