What is the car's forward acceleration,at a speed of 30m/s,when the driving force on the wheels is 650N

To determine the car's forward acceleration, you can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula for acceleration is:

acceleration = force / mass

In this case, the driving force on the wheels is given as 650N. However, the mass of the car is not provided, so let's assume it is unknown. It's important to note that without knowing the mass of the car, we won't be able to determine the exact acceleration.

If you have the mass of the car, you can substitute it into the formula to find the acceleration. However, if you don't have the mass, we can't calculate the acceleration precisely.

So, to summarize, in order to determine the car's forward acceleration, we need to know the mass of the car.
