What else can I help you with?
What quantity has changed velocity or speed for a car that travels north at 88 kmh and then turns east while continuing to move at 88 kmh?
The speed of the car has not changed. What has changed is the direction of travel. Velocity is a combination of speed and direction, so has changed. Newton's laws say that a body will continue to travel at its starting velocity unless acted on by an external force. There are two forces working here. 1 a force reducing the northward speed of 88 km/h to zero, and 2 a force accelerating the car eastward up to 88 km/h.
Rate of speed at which a raindrop falls from the sky?
20 mh-1 to 39 mh-1 above sea level.
What is the speed of the Coast Guard MH 60 helicopter?
It's top speed is about 185 mph
Is 88 kilometers per hour categorized as speed velocity or momentum?
Speed. A speed is a distance divided by time, such as miles/hour or meters/second An acceleration is a distance over a time squared, such as m/s^2 Momentum is the product of mass and velocity, and has units kg*(m/s)
What is speed in a given direction is called?
Speed in a given direction is velocity.
Are speed and velocity different?
SPEED has the speed only; while VELOCITY has the direction and the speed.
How is speed of a body related its velocity?
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
What is speed in a given direction?
Speed in a given direction is called velocity.
How do you find speed if you know the velocity?
Velocity is speed and direction
What is the difference betweenn speed and velocity?
Velocity is speed with a direction
What is instantaneous velocity or speed?
It is the speed or velocity at a particular instant.
What is the velocity of a wave that has frequency of 22 hz and a wave length of 4m?
The velocity of a wave can be calculated using the formula: velocity = frequency x wavelength. In this case, velocity = 22 Hz x 4 m = 88 m/s. Therefore, the velocity of the wave is 88 m/s.
