A bullet is shot straight in the air with an initial velocity of 139 ft/sec. Calculate how high (absolute value in ft) it will go up before it stops and reverses its motion. Assume g resistance is negligible. tion 5 1 pts A heavy object with negligible buoyancy enters water at a speed of 10 m/sec. Assuming a constant deceleration rate of -3.6 m/s2 in water, calculate how deep does it travel below the surface (absolute value of depth) before...
