Question 7 (1 point) A coal chute angled at 30 degrees to the horizontal releases 1.5 x 10# kg of coal to fill a stationary, empty 5.0x10 kg cart. The cart and coal move forward with a horizontal velocity of 2.0 m/s. m = 1.50 x 10' kg Before After Coal m =5.0 x 10 kg = 2.00 x 10' kg The speed of the coal along the chute is a.bc m/s. Record a.bc. Your Answer: Answer Question 8 (1 point) A 4.2 kg cannon ball is flying at 24.5 m/s [E] when it explodes into two fragments. One 2.8 kg fragment (A) goes off at 9.0 m/s [340 S of E]. What will be the magnitude of the velocity of the second fragment (B) immediately after the explosion? Assume that no mass is lost during the explosion. Round your answer to the nearest whole number Your
