Question

An object has an acceleration of 30.0 m/s/s. The mass of the object is tripled while the net force of the object is constant. What will the new acceleration be?​

a. 30.0 m/s/s
b. 15.0 m/s/s
c. 10.0 m/s/s
d. 90.0 m/s/s​

Answer 1

Known :

m1 = m

m2 = 3m1 = 3m

a1 = 30.0 m/s²

Solution :

Net force of the object is constant, so :

F1 = F2

m1 • a1 = m2 • a2

(m)(30.0 m/s²) = (3m)(a2)

a2 = 10 m/s²
