Look at Zeke.

Question

He’s riding his skateboard down a ramp. Assume that his acceleration is 0.8 m/s2. How much force does it take for him to accelerate at this rate? Zeke has a mass of 50 kg.

a
50 N
b
40 kg
c
40 N
d
62.5 N

Answer 1

To determine the force required for Zeke to accelerate at a rate of 0.8 m/s², we can use Newton's second law of motion, which states:

\[ F = m \cdot a \]

where:

• \( F \) is the force,
• \( m \) is the mass, and
• \( a \) is the acceleration.

Given:

• Mass \( m = 50 \) kg
• Acceleration \( a = 0.8 \) m/s²

Now, plug in the values:

\[ F = 50 , \text{kg} \cdot 0.8 , \text{m/s}² \] \[ F = 40 , \text{N} \]

Therefore, the correct answer is c) 40 N.
