Sagot :
Force
The force can be needed to stop him in 5 seconds is 2, 500 N.
You just need to multiply the mass and acceleration using this formula: F = ma
Solution:
F = (mass)(acceleration)
F = (500 kg)(5 m/s²)
F = 2, 500 N
Therefore, there are 2, 500 Newtons will be needed to stop him in 5 seconds.
