What is the truck's acceleration assuming the street is frictionless?

To calculate the truck's acceleration assuming the street is frictionless, I would need more information. To determine acceleration, one must know the forces acting on the truck and the truck's mass. Since the only information provided is that the street is frictionless, we can infer there is no frictional force opposing the motion of the truck. However, without additional details such as the force being applied to the truck (if any), the truck’s mass, or the change in its velocity over time, it’s not possible to calculate the acceleration.

The formula for calculating acceleration (a) is:

\(a = \frac{F_{net}}{m}\)

where: - \(F_{net}\) is the net force acting on the truck, and - \(m\) is the mass of the truck.

If the force applied and the mass of the truck are known, you can use this formula to calculate the acceleration. For example, if a force of 1000 newtons is being applied to a 1000-kilogram truck on a frictionless surface, the acceleration would be \(a = \frac{1000\,N}{1000\,kg} = 1\, m/s^2\).

If the truck is simply coasting (no additional forces), and we assume no other forces such as air resistance, the truck's acceleration would be zero (it would maintain constant velocity).
