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.

To calculate the acceleration of the wooden block, we use the expression F=ma where F is the force applied, m is the mass of the object and a is the acceleration. We calculate as follows:

F = ma
4.9 = 0.5a
a = 9.8 

Hope this answers the question. Have a nice day.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
