Bugs Bunny, having a mass of 75 kg, is pulled by Babs Bunny and Buster Bunny. Babs
Bunny tugs Bugs with a 50 N force to the north, towards a carrot cake stand. Buster pulls
Bugs with a 120 N force to the south, towards a basket ball court. There is a force of
friction of 15 N. What will be Bug's acceleration?

Answer:

a = 0.73 m/s²

Explanation:

Considering South direction to be positive and North to be negative. The unbalanced force on bugs bunny will be given as:

Unbalanced Force = Force of Buster - Force of Babs - Friction

Unbalanced Force = 120 N - 50 N - 15 N

Unbalanced Force = 55 N

But, from Newton's Second Law:

Unbalanced Force = ma

55 N = ma

where,

m = mass of Bugs Bunny = 75 kg

a = acceleration of Bugs Bunny = ?

Therefore,

55 N = (75 kg)a

a = 55 N/75 kg

a = 0.73 m/s²
