yes because his car have an m!
A stopped car has a speed of 0 m/s because it is not moving. Speed is the rate at which an object changes its position, so if the car is not changing its position, its speed is 0.
A car with a constant speed of 8 m/s will travel 8m in 8s.

E stands to Energy M stands for Mass C is the Speed of Light.It means the speed of light (in vacuum).
I got this out of my text book Glencoe Science Texas Science If you are riding in a car with the cruise control on, the speed doesn't change. In other words, the car moves at a constant speed. If you are running at a constant speed of 5 m/s, you run 5 m each second. Whether you give you speed for the first 5 m you run or the last 5 m, you cover each 5-m interval in 1 s. When you are traveling at a constant speed, the speed at any instant of time is the same.
The average speed of the car is 20 m/s. This is calculated by dividing the distance travelled (2 km = 2000 m) by the time taken (100 s).
The kinetic energy of the car can be calculated using the formula: KE = 0.5 * m * v^2, where m is the mass of the car (1600 kg) and v is the speed (12.5 m/s). Plugging in these values, the kinetic energy of the car is: KE = 0.5 * 1600 kg * (12.5 m/s)^2 = 125000 J.
If the speed of a car traveling south is increasing at 5 m/s, then its acceleration is 5 m/sĀ². This acceleration indicates the rate at which the car's velocity is changing per unit time.
Kinetic energy = 1/2 M V2At the lower speed, the car's KE is (500) (1)2 = 500 joulesAt the higher speed, the car's KE is (500) (2)2 = 2,000 joulesThe difference is the energy i.e. the work you have to put into itto raise the speed from 1 m/s to 2 m/s.(2,000 - 500) = 1,500 joules
The change in velocity is 26 m/s - 12 m/s = 14 m/s. The time taken for this change is 6 seconds. Therefore, the average acceleration is (change in velocity / time) = 14 m/s / 6 s = 2.33 m/s^2.
The "retardation" is more correctly referred to as "acceleration".Since the car is slowing down, the acceleration is negative.Its average value is(change in speed) divided by (time for the change) = (5 - 10)/2= -2.5 m/sec2.
