Acceleration is the rate of change of velocity of an object. Thus when the velocity ( direction or magnitude) of an object changes, we say that the particle is accelerating. Mathematically it is written as
a= 
The units of acceleration are m/s²
Acceleration can be positive or negative. If the velocity of an object increases, we call that as positive acceleration and if the velocity of an object decreases, we call that as the negative acceleration.
Answer:
Distance maximum
Xmax = 32m
Explanation:
Kinematics equation between velocities and distance:

For the distance maximum the final velocity is zero:
⇒ 
then, the equation becomes:

We replace the values for the initial velocity and acceleration
Vo=16m/s; a = -4m/s2
Finally:

Answer / Explanation:
B
Potential difference is measured using a device called a voltmeter . Just like ammeters, some types have a pointer on a dial, but most have a digital display. However, unlike an ammeter, you must connect the voltmeter in parallel to measure the potential difference across a component in a circuit.
Answer:
The correct choice is D. Concentric exercise can be hard on joints, so she should be very careful.
