Q-04 (10 points) Consider m1=782 grams cart is moving on horizontal surface (+x axis) with speed of 18.5 m/s. An object with my=250grams is suddenly dropped (moving on -y axis) into the moving cart and combined (cart + object) moving as a single object with different velocity after collision. There is no ay external force or mass lose during the collision. a) Calculate the speed of the carttobject system (after collision)? (4 points) b) Calculate total energy lost during the collision? (3 points) C) Find the average force (x direction) acts on object m2 during the collision (collision time is 0.170 s)? (3 points)
