Question

In the lab, you looked at speed-time graphs to determine the acceleration of the cart for each of the three fan speeds

Answer 1

Answer:

What was the acceleration of the cart with Low fan speed?  ⇒ 18.0 cm/s2

What was the acceleration of the cart with Medium fan speed?  ⇒ 24.0 cm/s2

What was the acceleration of the cart with High fan speed? 32.0cm/s2

Explanation:

Answer 2

Based on the speed-time graph, the acceleration at low, medium and high fan speed are 18 cm/s², 24 cm/s² and 32 cm/s² respectively.

How to determine the acceleration of this cart?

Mathematically, acceleration is calculated by using this formula:

a = [V - U]/t

Where:  

• V is the final velocity.

• U is the initial velocity.

• t is the time measured in seconds.

Based on the speed-time graph, the acceleration at low (A) fan speed is:

Final speed = 126 cm/s.

Initial speed = 0 cm/s.

Time = 7 seconds.

Acceleration = [126 - 0]/7

Acceleration = 126/7

Acceleration = 18 cm/s².

Based on the speed-time graph, the acceleration at medium (B) fan speed is:

Final speed = 144 cm/s.

Initial speed = 0 cm/s.

Time = 6 seconds.

Acceleration = [144 - 0]/6

Acceleration = 144/6

Acceleration = 24 cm/s².

Based on the speed-time graph, the acceleration at high (C) fan speed is:

Final speed = 160 cm/s.

Initial speed = 0 cm/s.

Time = 5 seconds.

Acceleration = [160 - 0]/5

Acceleration = 160/5

Acceleration = 32 cm/s².
