A scooter starting from rest moves wilth as constant acceleration for a time `/_\t_1`, then with a constant velocity for the next `/_\t_2` and finally with a constant deceleration for the next `/_\t_3` to come to rest with resect to the scooter wilthout touching any other part. The force exerted by the seat on the man is

A

500 N throughout the journey

B
