What else can I help you with?
What does the velocity of car A which is traveling at 50 ms West appear to be from your frame of reference?
Depends entirely on your frame of reference! If you are in a car traveling along side it at 50 ms, the car will appear to be standing still. If you are going the opposite direction at 50 ms, it will appear to be traveling at 100ms.
When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?
If the ball is traveling at a constant velocity of 50 m/s, then its acceleration is 0 m/s^2. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity, and therefore no acceleration.
What is a momentum of a object of 1kg and a velocity of 10 ms?
The momentum of an object with a mass of 1 kg and a velocity of 10 m/s is 10 kg*m/s. Momentum is calculated by multiplying the mass of the object by its velocity.
What is the momentum of a 20 kg object traveling at a rate of 5 ms?
Momentum = M V = 100 kg-m/s
Which describes an object in projectile motion Check all that apply. Gravity acts to pull the object down. The object moves in a straight path. The forward velocity of the object is 0 ms. The object a?
Gravity acts to pull the object down, The forward velocity of the object is 0 m/s.
A car traveling in a straight line has a velocity of 5.0 ms After an acceleration of 0.75 ms squared the cars velocity is 8.0 ms In what time interval did the acceleration occur?
4.0 s
What does the velocity of car A which is traveling at 50 ms West appear to be from your frame of reference?
Depends entirely on your frame of reference! If you are in a car traveling along side it at 50 ms, the car will appear to be standing still. If you are going the opposite direction at 50 ms, it will appear to be traveling at 100ms.
If the velocity of an object changes from 65 ms to 98 ms during a time interval of 12 s what is the acceleration of the object?
2.75 m/s
Is the velocity of an object changes from 65 ms to 98 ms during a time interval of 12 s what is the acceleration of the object?
2.75 m/s

What is the kinetic energy of an object with a mass of 30kg and a velocity of 20 ms?
6,000 J
What is a momentum of a object of 1kg and a velocity of 10 ms?
The momentum of an object with a mass of 1 kg and a velocity of 10 m/s is 10 kg*m/s. Momentum is calculated by multiplying the mass of the object by its velocity.
When an object in free fall is dropped from a building Its starting velocity is 0 ms Ignoring the effects of air resistance what is the speed in ms of the object after falling 3 seconds?
194fps
What is the momentum of a 20 kg object traveling at a rate of 5 ms?
Momentum = M V = 100 kg-m/s
The rate at which an object changes velocity and or directions?
Acceleration is the rate of change in velocity. (Velocity is speed+direction, it is a vector as well as acceleration). F=ma, where a is in ms^(-2).
The velocity of sound in air is 343 ms An ambulance is traveling east at 64.9 ms Behind it there is a car traveling along the same direction at 29.8 ms The ambulance driver hears his siren at a?
afrequency of the same as siren frequency as ambulance is the source and the observer this is not Doppler effect problem
