If the speed is constant at 50 mph, then the acceleration is 0.
My interpretation is that the car and any motion, like the graph, do not exist.
The van that is moving from 20 mph to 35 mph
Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.
As long as the 30 minute are spent driving in a straight line, the acceleration is zero.
The answer depends on when "then" is.
Stepping on the brakes of a moving car is an example of
The car's acceleration is in forward direction.
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
If the speed is constant at 50 mph, then the acceleration is 0.
The car is slowing down
If the speed of the car is decreasing while the car is still moving in a straight line, this means that the velocity and acceleration are in the same direction. This is because the car is decelerating, which results in a negative acceleration in the same direction as the velocity. This negative acceleration causes the speed of the car to decrease over time.
No. Definitely not
The acceleration of a car moving with uniform acceleration will remain constant. This means that the rate of change of its velocity will be consistent over time, resulting in a steady increase or decrease in speed.
Negative acceleration is the state of a body whose velocity in a specified direction is becoming smaller. If you apply the brakes while driving a car, the car (and you) will undergo negative acceleration in the direction in which the car was moving.
The acceleration of a moving car is the rate at which its velocity is changing over time. It can be positive (speeding up), negative (slowing down), or zero (constant speed). Acceleration is caused by forces such as engine power, braking, or changes in direction.
The acceleration of a car moving in a circle with uniform speed is directed towards the center of the circle and is called centripetal acceleration. This acceleration is given by the formula a = v^2/r, where v is the speed of the car and r is the radius of the circle.
