a) an object of mass 10 kg accelerating at 5 m/s2 -

The resultant force acting on the object is, = 110 N    

Explanation:

Given data,

The acceleration of the object, a = 5 m/s²

The mass of the object, m = 10 kg

Let the acceleration be in the horizontal direction.

The force acting on the object,

                         Fₓ = m x a

                              = 10 x 5

                              = 50 N

The gravitational force acting on the object,

                            F = mg

                               = 10 x 9.8

                                = 98 N

The resultant force on the object will be,

                                 (∵ θ = 90°)

Substituting,

                              = 110 N

Hence, the resultant force acting on the object is, = 110 N
