If a train is accelerating at a rate of 4km per hour per second and its initial velocity is 20km per hour what is its velocity after 30 seconds?
The train's velocity after 30 seconds can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Plugging in the values, final velocity = 20 km/hr + (4 km/hr/s * 30 s) = 20 km/hr + 120 km/hr = 140 km/hr. So, the train's velocity after 30 seconds is 140 km/hr.
An approaching storm is moving at 15 km per hr what do you need to know to determine its velocity?
To determine the velocity of the approaching storm, you need to know both the speed at which the storm is moving (15 km/hr) and the direction in which it is moving. Velocity is a vector quantity, so it includes both the speed and the direction of motion.
If a storm is moving at 15 kmhr what is needed for the velocity?
Well, isn't that just a happy little question! To find the velocity of the storm, you simply need to know the direction it's moving in. Velocity is a vector quantity that includes both speed (15 km/hr in this case) and direction. So, if you know the direction, you can describe the storm's velocity fully. Just like painting a beautiful landscape, understanding the full picture can help you appreciate the beauty of nature's creations.
What work is said to be done to increase the velocity of a car from 15 km per hour to 30 km per hour if the mass of the car is 1000 kg?
The difference between the before- and after- kinetic energy is(1/2) x (M) x (V22 - V12) = (500 kg) x 3 x (15 km/hr)2 = (1,500 kg) x (15 km/hr)2 =(1,500kg) x (15 km/hr x 1,000m/km x 1 hr/3,600 sec)2 = (1,500 kg) x (41/6m/sec)2 =6,250 joules
How long would it take for a car to travel a distance of 200 kilometers if it is traveling at a velocity of 55 km hr?
we need to travel 200km at 55 km per hour so that's 200 divided by 55 = 3.636 hours
If a boat is traveling east at 20 kmhr and the river it is on flows west at 5 kmhr what is the velocity of the boat?
20 km/hr - 5 km/hr = 15 km/hr
If a train is accelerating at a rate of 4km per hour per second and its initial velocity is 20km per hour what is its velocity after 30 seconds?
The train's velocity after 30 seconds can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Plugging in the values, final velocity = 20 km/hr + (4 km/hr/s * 30 s) = 20 km/hr + 120 km/hr = 140 km/hr. So, the train's velocity after 30 seconds is 140 km/hr.

To determine the velocity of the approaching storm, you need to know both the speed at which the storm is moving (15 km/hr) and the direction in which it is moving. Velocity is a vector quantity, so it includes both the speed and the direction of motion.
When a storm is moving at 15 kilometers per hour so what do you need to determine it's velocity?
Velocity= a speed and a direction The speed is 15 km/hr You still need a direction to make a velocity.
If a motorboat travels 25 km hr down a river whose velocity is 4 km hr what is the boats actual velocity?
21 km/h in the rivers frame of reference.
If a storm is moving at 15 kmhr what is needed for the velocity?
Well, isn't that just a happy little question! To find the velocity of the storm, you simply need to know the direction it's moving in. Velocity is a vector quantity that includes both speed (15 km/hr in this case) and direction. So, if you know the direction, you can describe the storm's velocity fully.

A car is traveling at a velocity of 70 km hr west to have the same velocity another car would have to travel at?
Another car would have to travel at 70 km/hr west.To have the same velocity, it must have the same speed toward the same direction.
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 work is said to be done to increase the velocity of a car from 15 km per hour to 30 km per hour if the mass of the car is 1000 kg?
The difference between the before- and after- kinetic energy is(1/2) x (M) x (V22 - V12) = (500 kg) x 3 x (15 km/hr)2 = (1,500 kg) x (15 km/hr)2 =(1,500kg) x (15 km/hr x 1,000m/km x 1 hr/3,600 sec)2 = (1,500 kg) x (41/6m/sec)2 =6,250 joules
A car travels west for 300 km in 6h that is the cars velocity?
50 km/hr
240km for 4 hours calculate the velocity?
60 km/hr
What is the speed of a train that travels a distance of 4800 km in 8.9 hr?
Velocity = distance/time = 4800 km / 8.9 hr = 539.3 kph
