Identify which of the following quantities are accelerations. 17 km/h120 m/s/s upwards0.2 m/s/s southwest7 m/s to the right5.3 m/s/s

To determine which of the given quantities are accelerations, we need to recall that acceleration is defined as the rate of change of velocity with respect to time. It has units of distance per time squared (e.g., m/s², km/h²).

Let's analyze each quantity:

1. 17 km/h: This is a measure of speed, not acceleration. It has units of distance per time (km/h), not distance per time squared.

2. 120 m/s/s upwards: This is an acceleration. It has units of distance per time squared (m/s²) and specifies a direction (upwards).

3. 0.2 m/s/s southwest: This is an acceleration. It has units of distance per time squared (m/s²) and specifies a direction (southwest).

4. 7 m/s to the right: This is a measure of velocity, not acceleration. It has units of distance per time (m/s), not distance per time squared.

5. 5.3 m/s/s: This is an acceleration. It has units of distance per time squared (m/s²).

Therefore, the quantities that are accelerations are:

• 120 m/s/s upwards
• 0.2 m/s/s southwest
• 5.3 m/s/s
