What is the average velocity of a truck that travels west 25 kilometers in 0.75 hours?
25/0.75 = 331/3 km per hourThat's the truck's average speed.If it spends the entire 45 minutes heading west, thenits average velocity is 331/3 km/hr west.
Which truck has more momentum a 2000kg truckor a 2kg truck?
That would depend on their velocity (speed with direction), since the formula for momentum is momentum=Mass*Velocity. If they are moving at the same Velocity, the heavier of the two would have greater momentum.
A truck driving east on a highway goes from the 42 mi marker to the 48 mi marker in 5.0 minutes. What is the truck's average velocity during this time?
To calculate the average velocity, first determine the distance traveled: 48 mi - 42 mi = 6 mi. Next, convert the time from minutes to hours: 5.0 minutes = 5/60 hours = 1/12 hours. The average velocity is then calculated as distance divided by time: 6 mi / (1/12 hours) = 6 mi * (12/1) = 72 mi/h. Therefore, the truck's average velocity is 72 miles per hour east.
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its direction.
When would the linear momentum of a truck be greater than that of a bus?
Since momentum equals mass times velocity, if the mass of the truck times its velocity is greater than the mass of the bus times the bus' velocity then the momentum of the truck will be greater than the momentum of the bus.
When is the average velocity equal to average of velocity for an object?
Always.
Does average velocity and average speed have the same number?
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
What is the momentum of a 5000kg truck at a rest?
The momentum of a truck at rest is zero because momentum is the product of an object's mass and velocity. Since the truck is not moving, its velocity is zero, resulting in zero momentum.
What is the mass of a truck with a ke of 4250 j and a velocity of 10s?
To calculate the mass of the truck, you need both the kinetic energy (KE) and the velocity. The formula to use is KE = 0.5 * mass * velocity^2. Rearranging this formula, we get mass = 2 * KE / velocity^2. Plugging in the values, the mass of the truck would be 850 kg.
A truck is traveling east on a highway at 80 km h What is velocity?
Velocity is speed and direction. Truck speed is 80 km/hr. Truck velocity is 80 km/hr going east. Its velocity is also -80 km/h going west, and 0 km/h going north or south.
What is the best definition of velocity?
The speed of something in a given direction.
