The velocity of a car changes from 15ms south to 5ms south in 2 seconds what is the acceleration of the car?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Substituting the values: acceleration = (5 m/s - 15 m/s) / 2 s = -5 m/s^2. Therefore, the acceleration of the car is -5 m/s^2, indicating that it is decelerating.
What else can I help you with?
Distinguish between velocity and acceration. Use an example to demonstrate your answer?
Velocity is the rate of change of displacement with respect to time, while acceleration is the rate of change of velocity with respect to time. For example, a car moving at a velocity of 50 km/h increases its velocity to 70 km/h in 5 seconds. The car experienced acceleration during this time period.
Does a change in direction change acceleration?
Not exactly, it can change a few degrees of its direction, but cannot change its velocity because if it stops, the force of motion that goes with it will demolish the car therefore it cannot change it's velocity.++++???? If you put the question in everyday language, it is asking "Can a car change direction while accelerating?"Yes it can, provided the driver is careful to keep the acceleration and instant speed within safe limits. I emphasise 'speed' because the direction hence velocity - a vector value - is changing.I have no idea of the point about the remark about stopping - the supposed consequences are fiction, and the question is about accelerating.
What is your velocity if you traveled 2000 m south in 400 seconds?
Velocity is distance/time. So, 2000/400 reduces to 5 m/s, but since velocity is a vector, direction MUST be stated along with the speed we just calculated. The final answer is 5 m/s South (or 270 degrees).
If the speed of a car traveling south is increasing 5 ms it and its acceleration is?
If the speed of a car traveling south is increasing at 5 m/s, then its acceleration is 5 m/s². This acceleration indicates the rate at which the car's velocity is changing per unit time.
What would a negative acceleration tell you about the object in motion?
the car is at a constant speed---------------------------------------------------------I'm pretty sure that if the acceleration is negative, the car is slowing down. But if the velocity is negative, the car is either heading south or down (velocity refers to speed and direction.. according to my physics teacher).

What are the similarities between speed and acceleration?
The two words are synonyms. However, in physics there is a more precise definition, which is a change in an object's position in a specified direction with time. So in everyday language we could say the speed of the car is 60 miles per hour, but in physics you'd say its velocity is 60 miles per hour North/South/East/West.
April swims 50 m north and then turns and swims 20 m back to the south what is her velocity if it takes her 60 seconds-?
If April swam 50 M North then swam 20 M South back then her velocity would be 16.66. This is a math problem.
Tom walked 450 m south He then turned and walked 150 m to the north in 600 seconds What was his velocity?
He walked 600m in 600 seconds so his velocity is 1m/s (one metre per second)

Ed biked home from school in 400 seconds. his home in located 2000 m south of the school. what was his velocity?
5 m/s south
April moves from a position 5 m north of her front door to a new position that is 3 m south of her front door if this movement takes her 4 seconds what is her velocity?
Displacement: 8 m south Time: 4 seconds Therefore velocity = 2 metres per second Southwards.
If A sailboat sails down the James River due South at exactly 15 mph for 1 hour. Is the sailboat accelerating?
No, since the sailboat maintains a constant velocity of 15 mph in a southerly direction, it is not accelerating. Acceleration involves a change in velocity over time, so if the velocity remains constant, there is no acceleration.
Can an object have a northward velocity and southward acceleration?
Yes, an object can have a northward velocity and southward acceleration. This situation occurs when the object is moving northwards but its speed is decreasing or it is changing direction towards the south.
