What else can I help you with?
Car with a mass of 1100 kg is moving with a velocity of 30m's due east what is its momentum?
Momentum = (mass) x (velocity) = (1,100) x (30) = 33,000kg-m/sec due east
If a car is traveling at a constant speed but is going around a curve what can you say about the cars motion?
The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.
What will happen to the velocity of the car as sand is loaded onto it?
The velocity of the car will decrease as sand is loaded onto it due to the increase in mass. This increase in mass requires more force to accelerate the car to maintain the same velocity. Additionally, the added weight may affect the car's ability to overcome friction and air resistance, further reducing its velocity.
Why Does a car have a higher momentum because it is traveling faster?
A car has higher momentum when traveling faster because momentum is the product of an object's mass and velocity. When a car is moving at a faster speed, it has a higher velocity, resulting in a greater momentum due to the increased product of mass and velocity.
Which of these objects has the most mechanical kinetic energy a spring compressed a rock sitting on a cliff a bycicle going 10mph a car going 60 mph?
Kinetic energy is energy available due to velocity, so you can exclude the compressed spring and the rock sitting on a cliff. As far as the bicycle vs the car, the car is the easy winner. EK = 0.5 m v2 Since both the mass (m) and the velocity (v) of the car exceeds that of the bicycle, it is clear that EK-Car is much greater than EK-Bicycle.

What is the velocity of a car that traveled 300 km east in 2 hours?
150 km per hour due East (or even -150 km per hour due West).
Do speed and velocity have same meaning?
No. It's confusing unless you're into physics or mathematics but velocity is a vector quantity with speed is one aspect. Velocity includes speed and the direction of motion. A car is going 60 miles per hour as speed. A car is going 60 MPH due north is velocity.

What is the difference between an object's speed and an object's velocity?
Speed is a scalar quantity and thus a general term; if a car is traveling at 60 mph that is its speed;Velocity is a vector quantity that has speed and direction associated with it. If a car is traveling at 60 mph due east that is its velocity.The two terms are often used interchangeably.
One car travels due to east at 40km per h and a second car travels north at 40km per h are their velocities equal?
No. "Velocity" includes a magnitude and a direction. If any of the two are different, then the velocities are also different.
Is it possible that velocity of an object be in a direction other than the direction of acceleration?
Yes. Acceleration is change in motion. Velocity -- speed and a vector -- combined with mass provide momentum. While such directions are meaningless, imagine you are in space and there is (to get a picture and bearing of it) a 'north/south' direction and an 'east/west' direction. Suppose you were going due north at a constant 100 km/h (not accelerating), but you turned 90 degrees east and began accelerating in that direction at 1 km/s2. You are not suddenly travelling due east just because you are accelerating east, but are slowly arcing east of north as you continue the acceleration. In fact, to eventually go due east after starting off due north, you would actually have to steer a bit south of east and accelerate in that direction as simply accelerating due east after having been moving due north will make east an asymptote (a goal you can get close to but not quite reach). By steering and accelerating a bit south of east, the asymptote is along that vector and making due east eventually achievable.

What direction is right if you are going north?
If you are going or facing due north, then east is to your right.
How can the velocity of a car during breaking at a constant acceleration against time from the moment of applying the breaks?
The velocity of a car during braking with constant acceleration can be calculated using the kinematic equation: final velocity = initial velocity + acceleration * time. As the car brakes, the initial velocity decreases to 0 m/s (assuming the car comes to a stop), and the acceleration due to braking is negative. Therefore, the equation becomes: final velocity = -acceleration * time.
