Answer:
1 m/s²
Explanation:
The following data data were obtained from the question:
Net force (F) = 10 N
Initial mass (m1) = 5 Kg
Initial acceleration (a1) = 2 m/s²
Final mass (m2) = double the initial mass = 2 × 5 = 10 kg
Final acceleration (a2) =?
The final acceleration of the object can be obtained as follow:
Recall:
Force (F) = mass (m) × acceleration (a)
F = m × a
Keeping the force constant, we have
m1a1 = m2a2
With the above formula, we can obtain the final acceleration of the car as follow:
Initial mass (m1) = 5 Kg
Initial acceleration (a1) = 2 m/s²
Final mass (m2) = 10 kg
Final acceleration (a2) =?
m1a1 = m2a2
5 × 2 = 10 × a2
10 = 10 × a2
Divide both side by 10
a2 = 10 /10
a2 = 1 m/s²
Therefore, the final acceleration of the car will be 1 m/s²
