Atticus Nicholson · Answer 1

acceleration = 1 m/s²

Explanation:

A) Mass = Scalar, Displacement = Vector quantity, Velocity = Vector quantity, Acceleration = Velocity

B) Vector quantities are quantities that have both magnitude and direction while scalar quantities are quantities that have only magnitude and but no direction.

c) From the first equation of motion, v = u + at

since the object starts from rest, u = 0 m/s

time, t = 5 seconds

5 = 0 + 5a

a = 5/5

a = 1 m/s²
