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
40 N
b
62.5 N
c
50 N
d
40 kg

Answer 1

To find the force needed for Zeke to accelerate at 0.8 m/s², you can use Newton's second law of motion:

$$F=m\cdot a$$

where:

• $F$ is the force,
• $m$ is the mass,
• $a$ is the acceleration.

Here, Zeke's mass $m=50$ kg and the acceleration $a=0.8$ m/s².

Now, plugging in the values:

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

So, the required force is 40 N.

The correct answer is a) 40 N.
