In which case, the object is speeding up:
Correct answer: B. Velocity is neagtive acceleration is negative
- A. Velocity is positive acceleration is negative
- B. Velocity is neagtive acceleration is negative
- C. Velocity is negative acceleration is zero
- D. Velocity is negative acceleration is positive
Explanation
body is speeding because both velocity and acceleration are in same direction

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
