initial velocity u = 90 km/s = 25 m/stime t = 5 secmass m = 200 kg final velocity v = 0 m/s
Formula for velocity is v = u + at
Substitute values of all the variables in the above equation
0 = 25 + a * 5-5a = 25a = -5
Therefore acceleration = -5m/s²
Formula for Force is F = ma. Substituting the values for mass and acceleration, we get the force.
F = 200*-5F = -1000 N
Therefore force is -1000 N
