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
