Answer:
No, it cannot. The car needs the friction of the surface to drive because the car pushes the surface backwards, and the surfaces makes a reaction force pushing the car forward, and that works because of the friction. In a frictionless surface the tires would rotate in the same place
A change in an object's speed has a(n) _________ effect on its kinetic energy than a change in its mass = <span>A greater effect.</span>
21N
Explanation:
Given parameters:
Mass of wagon = 14kg
Acceleration = 1.5m/s²
Unknown:
Net force on wagon = ?
Solution:
Force is a pull or push on a body that causes a body to change its state. It is expressed as:
Force = mass x acceleration
Force on wagon = 14 x 1.5 = 21N
