Answer: 4m/s²
Explanation:
force of cart = 10 N
friction force = 2 N
mass of cart = 2 kg
cart acceleration = ?
Net force = (Force acting on cart - Friction force)
Net force = 10N - 2N = 8N
According to Newton's second law of motion, net force depends on the acceleration and mass of an object.
Thus, Net force = mass x acceleration.
Since net force is obtained, apply the Newton 2nd law to get the cart acceleration .
Net force = ma
8N = 2 kg x a
a = 8N / 2kg
a = 4m/s²
