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.

Question

A) 50 N
B) 40 kg
C) 62.5 N
D) 40 N

Answer 1

To find the force required to accelerate Zeke on the skateboard, we can use Newton's second law of motion, which states that \( F = m \cdot a \), where \( F \) is the force, \( m \) is the mass, and \( a \) is the acceleration.

Given:

• Mass \( m = 50 , \text{kg} \)
• Acceleration \( a = 0.8 , \text{m/s}^2 \)

We can plug these values into the equation:

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

So the force required for Zeke to accelerate at this rate is 40 N.

The correct answer is: D) 40 N.
