Answer:
2s
Explanation:
Given parameters:
Acceleration of the truck = 15m/s²
change in Velocity = 30m/s
Unknown:
Time taken for the body to slow down = ?
Solution:
Acceleration is the rate of change of velocity ;
Acceleration = [tex]\frac{change in velocity}{time}[/tex]
time = [tex]\frac{change in velocity }{acceleration}[/tex]
Now insert the parameters and solve;
time = [tex]\frac{30}{15}[/tex] = 2s
