Question

T=163 N (k) Suppose m1-5 kg and m2-9 kg. What is the value of the acceleration? (I) Suppose that m2 starts from rest at a height of 5 m. Use the kinematic equations to determine how long it takes for m2 to hit the ground 1.889 s Additional Materials Newton's Second Law Appendix 6. -10 points My Notes A bullet is shot into a block of plastic. The bullet penetrates the block 0.5 m. The mass of the bullet is 10 g. It is traveling with a speed of 460 m/s before it hits the block. (a) Use kinematic equations to find the magnitude of the acceleration on the bullet as it is penetrating the block (ignore gravity, and assume that the force on the bullet as it penetrates the block is constant) (b) Use Newton's Second Law to find the magnitude of the force exerted on the bullet by the plastic block.
