1.The time rate of change of position of a body in a particular direction
2. And by an arrow.
You divide the distance traveled by the time.
It is 20 km per hour, due North.
Speed = Distance divided by Time. So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour. Velocity is speed and direction, so the velocity is 30 mph Northbound.
Velocity = 790.514 m/s North (rounded)The idea is to divide the distance by the time.
We're not completely sure what you mean by "per hour per second". Going just by what we see in the question, it's an acceleration, not a velocity. "Six miles per hour north" would be a velocity.
50km/hour North.
The average velocity during that period of time is 100 kilometers per 2 hours north. It may also be stated as 50 kilometers per hour north.
The train's speed is 250 km/h (500 km / 2 hours). The velocity would be 250 km/h north, considering velocity is a vector quantity that includes both speed and direction.
With the information given, it's not possible to calculate what it is now. But during that 90 minutes, its average velocity was 50 kph north.
The speed of the car is the rate at which it covers distance, measured in kilometers per hour. The velocity of the car is the rate at which it changes position, including direction, measured in kilometers per hour in a specific direction. Without the value of distance traveled or the specific direction (north) covered, the speed and velocity of the car cannot be determined.
The velocity of the car is 65 miles per hour. This is calculated by dividing the distance traveled (260 miles) by the time taken (4 hours). Since direction is not specified in the calculation of velocity, the northeast direction does not affect the final answer.
You divide the distance traveled by the time.
4 hours
It is 20 km per hour, due North.
Consider the two statements: (1) The car left town and traveled 50 km. (2) The car left town and traveled 50 km NORTH. In the first statement we are merely talking about the distance traveled We do not know which way the car went. This is speed. SPEED is only a magnitude. In the second, we are giving more info by adding the DIRECTION in which the car traveled. This is VELOCITY. VELOCITY gives speed together with DIRECTION. You can see that VELOCITY is more informative than SPEED. In everyday life, people in the streets use the two terms interchangeably, but in science and engineering the distinction is important.
Speed = Distance divided by Time. So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour. Velocity is speed and direction, so the velocity is 30 mph Northbound.
a) What is his total displacement? b) What is his average velocity? a) let displacement First 35 mines d = v t d = (KM/ h x min)/ 60 min = 49.6 Km Next 2 hours 49.6 Km +130 Km = 179.6 Km, His displacement is 179.6 Km (North) b) His average velocity is v = d / t t = min + min + min = 35 + 15 + 120 = 170 mines v = d / t = (179.6 Km / 170 min ) x ( 60 min / 1 hour ) = 63.4 Km / h (North)
