Answer:
Given,
The mass of the vehicle m=100kg
The initial velocity u=5m/s.
The time required to stop the vehicle t= 10 *1
sec i.e 0.1second.
The final velocity of the vehicle v=0m/s.
As per Newton's second law of motion, we know that force is equal to rate of change of momentum.
F= dt dp
Here F and p stands for force and momentum
=m tv−u
=100
0.1[0−5] N
=−5000N
The Negative sign indicates the force is in opposite direction
Therefore, F=5000N
hope it helps!!✌️✌️
