Question

An athlete initially at rest takes 2 seconds to reach its maximum speed of 36 km per hour. The magnitude of:

A. Acceleration
B. Velocity
C. Distance covered
D. Displacement

Answer 1

The displacement of an athlete can be calculated using the formula: d = vi*t + 0.5at^2. By substituting the values into the equations, the displacement of the athlete can be calculated.

Step-by-step explanation:

The displacement of an athlete can be calculated using the formula:

d = vit + 0.5at2

Where:

• d is the displacement
• vi is the initial velocity (0 m/s)
• t is the time taken to reach the maximum speed (2 seconds)
• a is the acceleration

Since the athlete is initially at rest, the initial velocity is 0 m/s.

The acceleration can be calculated using the formula:

a = (vf - vi) / t

Where:

• vf is the final velocity (36 km/h)
• vi is the initial velocity (0 m/s)
• t is the time taken to reach the maximum speed (2 seconds)

By substituting the values into the equations, the displacement of the athlete can be calculated.
