The speed of a bullet as it travels down the barrel of a rifle toward the opening is given by -(-4.05x 107)2(2.45 x 105)t, where v is in meters per second and t is in seconds. The acceleration of the bullet just as it leaves the barrel is zero. (a) Determine the acceleration and position of the bullet as a function of time when the bullet is in the barrel. (Use t as necessary and round all numerical coefficients to...
The speed of a bullet as it travels down the barrel of a rifle toward the opening is given by v = (−4.80 ✕ 107)t2 + (2.45 ✕ 105)t, where v is in meters per second and t is in seconds. The acceleration of the bullet just as it leaves the barrel is zero. (a) Determine the acceleration and position of the bullet as a function of time when the bullet is in the barrel. (Use t as necessary and...
A muzzle-loading rifle fires 22LR bullets such that as they travel down the barrel of the rifle their speed is given by v (-4.75 10t2(2.55 x 105)t, where v is in meters per second and t is in seconds. The acceleration of the bullet just as it leaves the barrel is zero. (a) Determine the acceleration (in m/s) and position (in m) of the bullet as a function of time when the bullet is in the barrel. (Use the following...
As depicted in the figure, a barrel rolls down a ramp and flies off the end with velocity o 15 (m/s) at an angle 0 20 with respect to the horizontal. The barrel lands a distance L along the slope (measured from the end of the ramp where the barrel becomes airborne). Note that the slope is inclined at p 30 relative to level ground a) How far down the slope, L, does the barrel land, and how long, T,...
Question 2 What is the EXACT output of this code: class B { public B{ System.out.print("B"); } } class A extends B{ public A(int t) { super(); System.out.print("A"); } } public class Test{ public static void main(String[] args) { A a = new A(3); } }
A 40-gallon barrel is filled completely with pure water. Salt water with a concentration of 0.3 lb/gal is then pumped into the barrel, and the resulting mixture overflows at the same rate. The amount of salt in the barrel at time t is given by Q(t) = 12(1 − e−0.07t) where t is measured in minutes and Q(t) is measured in pounds. (a) How much salt is in the barrel after 5 min? (Round your answer to two decimal places.)...

The speed of a bullet as it travels down the barrel of a rifle toward the open end is given by: v-(-5.00 x 107)t2 + (3.00 x 1 jt where v is in m/s and t is in seconds. The acceleration of the bullet just as it leaves the end of the barrel is zero. a. Find the position x and acceleration a of the bullet as functions of time while it is still within the...
