Question

You are in a car with a mass of 50kg and it crashes into a wall. You are not wearing a seatbelt. The car hits and bounces off a wall with a force of 600N and then bounces back to a stop. How much acceleration in m/s2 were you when you hit the wall?

a) 50kg
b) 0m/s²
c) 12m/s²
d) 600m/s²

Answer 1

Using Newton's second law of motion, we calculate the acceleration as the force divided by the mass of the car. With a force of 600N and a mass of 50kg, the acceleration upon hitting the wall is 12 m/s².

Step-by-step explanation:

To determine the acceleration you experienced when you hit the wall, we can use Newton's second law of motion, which states that Force equals mass times acceleration (F = ma). In this case, the force is given as 600 N and the mass of the car (and presumably the object that the force is applied to, which includes you) is 50 kg.

Using the formula, we simply rearrange it to solve for acceleration (a):

a = F / m

Acceleration (a) = 600 N / 50 kg = 12 m/s2.

Therefore, the correct answer is c) 12 m/s2.
