A bullet is accelerated down the barrel of a gun by hot gases produced in the combustion of gun powder. What is the average forc

elena-14-01-66 [18.8K]

Answer:4.259 kN

Explanation:

Given

mass of bullet $m=0.02 kg$

final velocity of bullet $v=575 m/s$

time taken $=2.7 ms\approx 2.7\times 10^{-3} s$

We know

$Impulse=F_{avg}\cdot t=change\ in\ momentum$

thus

Initial Momentum $(P_i)=m\times 0$

Final Momentum $(P_f)=m\times v=0.02\times 575$

$P_f=11.5 kg-m/s$

$F_{avg}\times 2.7\times 10^{-3}=P_f-P_i=11.5$

$F_{avg}=4.259\times 10^3$

$F_{avg}=4.259 kN$

A person hits a 45-g golf ball. The ball comes down on a tree root and bounces

Verizon [17]

Answer:

Maximum height, h = 10 m

Explanation:

It is given that,

Mass of golf ball, m = 45 g = 0.045 kg

The ball comes down on a tree root and bounces straight up with an initial speed of 14.0 m/s.

We need to find the height the ball will rise after the bounce. It is based on the conservation of energy such that,

$\dfrac{1}{2}mv^2=mgh$

h is maximum height raised by the ball

$h=\dfrac{v^2}{2g}\\\\h=\dfrac{(14)^2}{2\times 9.8}\\\\h=10\ m$

So, the ball will raised to a height of 10 meters.
