Denise is conducting a physics experiment to measure the acceleration of a falling object when it slows down and comes to a stop. She drops a wooden block with a mass of 0.5 kilograms on a sensor on the floor. The sensor measures the force of the impact as 4.9 newtons. What’s the acceleration of the wooden block when it hits the sensor? Use F = ma.
A.
2.45 m/s2
B.
4.4 m/s2
C.
5.4 m/s2
D.
9.8 m/s2

Answer:

D!

Explanation:

Using the formula F = ma, you plug in 4.9 for F (force), and 0.5 for m (mass), then solve for a (acceleration).

Answer:

9.8 m/s^2

Explanation:

F=ma

The force is 4.9 N

The mass is 0.5 kg

The acceleration is what we are trying to figure out.

(Now, plug into the equation)

4.9= 0.5a

Take 4.9/0.5 to find the value of a, which is 9.8m/s^2
