Calculate the acceleration of a 2kg block on a horizontial friction-free air table when you exert a horizintial net force of 20N
net force=mass*accelerationi
acceleration=netforce/mass
To calculate the acceleration of a 2kg block on a horizontal friction-free air table when a horizontal net force of 20N is exerted, we can use Newton's second law of motion.
Newton's second law states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.
The formula for Newton's second law is:
F = m * a
Where:
F is the net force (20N in this case)
m is the mass of the block (2kg)
a is the acceleration
To find the acceleration, we rearrange the formula:
a = F / m
Plugging in the given values:
a = 20N / 2kg
Dividing 20N by 2kg gives us:
a = 10 m/s²
Therefore, the acceleration of the 2kg block on the horizontal friction-free air table, when a horizontal net force of 20N is exerted, is 10 m/s².
