Answer: 34.78 m/s .
In physics, momentum is a quantity that can be calculated by multiplying the mass and velocity of the object involved. Momentum is expressed by the letter p. So momentum equals mass times velocity or p = m x v . Therefore, if any object of any mass is not moving, its momentum is zero because its velocity is zero.
The answer is C. You divide 4000 kg/s by 115 kg.
The velocity of a skateboarder who momentum who is a 100 kg is 6.67 m/s .
120 N is required to accelerate a body with a mass of 15 kilograms at a rate of 8 m/s2. This answer has been confirmed as correct and helpful.
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement .
Defining Scalar and Vector Quantities
Scalar is the measurement of a unit strictly in magnitude . Vector is a measurement that refers to both the magnitude of the unit and the direction of the movement the unit has taken.
Momentum is a measurement of mass in motion. Any object that is moving has momentum. In physics, momentum of an object is equal to the mass times the velocity .
When objects collide, the energy transfers from one object to the other . Energy is the ability to do work (or in more simple terms: energy makes things happen). The amount of energy transferred during a collision depends on the weight and speed of the moving object.
Momentum can be thought of as the “power” when a body is moving, meaning how much force it can have on another body. For example, a bowling ball (large mass) moving very slowly (low velocity) can have the same momentum as a baseball (small mass) that is thrown fast (high velocity).
The answer is C. You divide 4000 kg/s by 115 kg .
Overall average skateboard speed is around 9 mph including all types of skills, terrain, and setups. Typical skateboard speed falls in the 5 – 12 mph range. Experienced skateboarders frequently commute at average speeds of 7 – 8 mph on 1-2 miles flat trips.
The acceleration of the book is 40 m/s .
If an object has a mass of 20 kg, The force of gravity acting on earth is 196N .
Force required to accelerate the body is 6N .
Forces cause things around you to move . Force is measured in Newtons, which are units that equal 1 kg * m/sec2. You can calculate the amount of force that an object experiences with the equation force = mass * acceleration. If you know any two of these values, you can use them to find the third.
