Answer 2

To solve this problem, we need to convert the given values into consistent units and then use the appropriate formulas. Let's do that step by step:

Given values:

• V0 = 72 km/h (initial velocity)
• V = 0 m/s (final velocity)
• T = 5°C (temperature)

Step 1: Convert velocity units To convert km/h to m/s, we need to multiply the value by (1000 m / 1 km) and then divide it by (3600 s / 1 h):

V0 = 72 km/h * (1000 m / 1 km) / (3600 s / 1 h) ≈ 20 m/s

Step 2: Calculate acceleration Since the final velocity (V) is 0 m/s and the initial velocity (V0) is 20 m/s, we can use the following kinematic equation:

V^2 = V0^2 + 2a * S

Where V = final velocity, V0 = initial velocity, a = acceleration, and S = displacement (distance traveled).

Given that V = 0 m/s and V0 = 20 m/s, we can solve for a:

0^2 = (20 m/s)^2 + 2a * S 0 = 400 m^2/s^2 + 2a * S

Step 3: Calculate the displacement (S) Now, let's calculate the displacement (S). We already know that the temperature (T) is 5°C, but we need additional information to find the displacement. There seems to be a missing variable or equation in the problem statement related to the temperature. Please provide more information or clarify the problem, and I'll be happy to help you further.
