Question

which of the following scenarios experience unbalanced forces? a cat jumping on the counter a book on a bookshelf a cup sitting on a table a bike accelerating 1.0 m/s^2 a house built on a concrete slab a person slipping on a banana peel the cup and the house the book and the bike the cat and the person. the bike and the person

Explanation:

Unbalanced forces cause a change in motion. A cat jumping changes its state of motion, a bike accelerating has a non - zero acceleration which implies unbalanced forces, and a person slipping is also experiencing a change in motion. Objects at rest like a book on a bookshelf, a cup on a table, and a house on a concrete slab have balanced forces acting on them (gravity and normal force are balanced).

Answer:

D. the bike and the person
