Question

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 its speed is reduced to 7.0m/s 2

Answer 1

Question 3, using third equation of motion,

v^{​​​​​​2}​​​​​ = u^{​​​​2} + 2as
