A ball of mass 100g thrown by a man moves at a velocity of 100m/s. what is the momentum? need the answer step by step plssss!! i need it fast!!!!!!!
Explanation:
Mass of the ball= 100 g = 0.1 kg
Velocity of the ball before collision=10 m/s
Momentum of the ball before collision, p(i)=mv= 0.1×10=1 kgm/s
Since, ball returns back with same velocity
Therefore, velocity of ball after collision = -10 m/s (-ve sign due to opposite direction)
So, momentum of ball after collision,p(f) = 0.1 ×(-10) = -1 kgm/s
Now, Impulse generated in the ball= change in momentum= p(f)-p(i)= -1–1= -2 kgm/s
What does this mean?
Pick one of the statistics shared that does not fit your current paradigm and share how you think you would feel if it was part of your own reality?
it's not letting me comment my original answer
I think it's saying
choose one of the options that doesn't take place in the current reality
then explain how things would be different and how it would feel if it was real life

A car driver sees a rabbit on the road. The driver makes an emergency stop after he sees the rabbit. Figure given shows the speed of the car from the time the driver sees the rabbit until the car stops. ) Calculate the distance that the car travels in the first 0.5 seconds.
2. A car of mass 1000 kg is moving with a velocity of 10 m/s. If the velocity-time graph for this car is a horizontal line parallel to the time axis, then the velocity of the car at the end of 25 s will be:
Answer:
car go vroom
Explanation:
Cara is swimming in a river. She can swim downstream up to a maximum speed of 66 meters per-minute. If she is swimming downstream at half of her maximum speed, how far will she swim in 13 minutes?
During a hockey game, the puck slid from the center line directly to the goal line in 1.5 seconds. The center line is 27 meters from the goal line. As the puck slid, it was chased by a hockey player skating at 9.5 meters per second. What was the puck's velocity?
Answer: The pucks velocity was 18 meters per second.
Explanation: First I divided 27 by 3 because of the 1.5 seconds and the i multiplied my answer by 2 and got that it traveled 18 meters in 1 second.
During a hockey game, the puck slid from the center line directly to the goal line in 1.5 seconds. The center line is 27 meters from the goal line. As the puck slid, it was chased by a hockey player skating at 9.5 meters per second. And the puck's velocity is 18 m/s.
What is Average velocity?
Average velocity can be defined as the average rate of change of displacement with respect to time. Average velocity is a measure for distance traveled in a given time.
We can calculate the average velocity by the rule
v = s/t (m/s)
where s is the displacement and t is the time
Mathematically,
speed = distance/ time
The puck traveled a distance of 27 m in 1.5 seconds
The speed of the puck is thus;
27/1.5 = 18 m/s
Thus, the puck's velocity can be calculated as 18 m/s.

What is soil erosion
Answer:
Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage.
Answer:
It is the breakdown of soil due to natural processes
Explanation:
Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide
