An object has an acceleration of 4.0 m/s/s.

Question

An object has an acceleration of 4.0 m/s/s. If the net force experienced by the object is increased by a factor of 2.5 and if the mass of the object increased by a factor of 3.3, thens the new acceleration would be _______ m/s/s.

Answer 1

F = ma

F/m = 4.0ms^-2

F_new = 2.5F

m_new = 3.3m

F_new = m_new x a_new

a_new = F_new / m_new = 2.5F / 3.3m = 2.5/3.3 x F/m , but F/m = 4.0 ms^-2

a_new = 2.5/3.3 x 4.0 = 3.0 ms^-2
