A 10 g bullet is fired into, and embeds itself in, a 2 kg block attached to a spring with a force constant of 19.6 n/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block and

99. ## Physics

A block of mass 17.9 kg supported by a vertical massless cable is initially at rest. The block is then pulled upward with a constant acceleration of 2.01 m/s2. What is the tension in the cable? What is the magnitude of the net force acting on the mass?

hi im having trouble with this i think the answer is zero! can u guys double check ty if there are three blocks tied together, with a force enacted on the first block, the net force on the middle block is..... a. zero b. F/3 c. F/2 d. 2F/3 e. F This cannot
