Given:
• Acceleration, a = 30 m/s²
,
• Distance, d = 74 m
,
• Force, F = 600 N
,
• Frictional force, Ff = 120 N
Let's find the mass of the cart.
To find the mass of the cart, apply Newton's Second Law:
Where:
Fnet is the net force
m is the mass
a is the acceleration.
To find the net force, we have:
Thus, we have:
Solving further:
Therefore, the mass of the cart is 16 kg.
• ANSWER:
16 kg
