DIRECTIONS: Solve for the given problems. Use the GRESA method. Please answer on a piece of paper and upload here the image of your answer. Car A of mass 2000 kg moving at 20 m/s, East overtakes car B of mass 1250 kg and moving at 60 km/h East. Car A collides with car B. Find the velocity of Car B if Car A moves 10 m/s after collision.

s after collision.
Explanation:
Given,
Mass of car, M=2000kg
Velocity, V=72×185=20ms−1
Apply kinematic equation of motion
v2−u2=2as
0−202=2a×20
a=−10ms−2
Breaking force, F=ma=2000×10=20 kN
Apply first kinematic equation
v=u+at
t=av−u=−100−20=2 sec
Breaking force is 20 kNand time is 2sec.
