Quiz4u! Find the acceleration vector:

Question

Suppose that various forces are acting on a moving object whose mass is 20kg. Suppose that the net force, in Newtons, is given by the vector [-16, 22]

Find the acceleration vector of the object. Choose the closest answer.

Possible Answers:

[-0.8, 1.1]

[-1.5, 2.3]

[-0.4 1.7]

[-0.3, 2.3]

[-1.5, 2.5]

Answer 1

Acceleration is given by force over mass.

a = F / m

[-16, 22] N / 20 kg

= [-0.8, 1.1] m/s²
