How long does it take a bullet to accelerate from rest to aspeed of 343 m/s if the blast from the gun can acceleratethe bullet at a rate of 1.25 × 105 m/s2?

A bullet travels at 850 m/s.  How long will it take the bullet to go 1,000 m? (round to the nearest 10th please)

A bullet of mass 5 gram is charged to 1 C. Through what potential difference it must be accelerated, so that it can acquire a speed of 100 m/s, starting from rest?

a 3.30 g bullet is fired horizontally at two blocks at rest on a frictionless tabletop. The bullet passes through the first block, with mass 1.20 kg, and embeds itself in the second, with mass 1.80 kg. Speeds of 0.630 m/s and 1.40 m/s, respectively, are thereby given to the blocks (Fig. 7-28b). Neglect the mass removed from the first block by the bullet. Figure 7-28 (a) Find the speed of the bullet immediately after it emerges from the first block. m/s

A 4.80 g bullet moving at 660 m/s strikes a 700 g wooden block at rest on a frictionless surface. The bullet emerges, traveling in the same direction with its speed reduced to 420 m/s. What is the resulting speed of the block? m/s

A 16.5 kg rifle, initially at rest, fires a 380 g bullet at a muzzle velocity of 770 m/s. Assumethat the time of acceleration along the barrel is 44.0 milliseconds.a) What is the average force on the bullet?
