Answer:
3N
Explanation:
Given parameters:
Mass of toy car = 6kg
Initial velocity = 0m/s
Final velocity = 2m/s
Time = 4s
Unknown:
Net force = ?
Solution:
The net force is given by;
Force = mass x acceleration;
Force = mass x [tex]\frac{v - u}{t}[/tex]
v is the final velocity
u is the initial velocity
t is the time taken
Now insert the parameters and solve;
Force = 6 x [tex]\frac{2 - 0}{4}[/tex] = 3N
