A 0.0600-kilogram ball traveling at 60.0 meters per second hits a concrete wall. What speed must a 0.0100-kilogram bullet have i

GarryVolchara [31]

Answer:

the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is 360 m/s

Explanation:

The computation of the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is as follows:

The ball momentum is

$\Delta Q = mv\\\\\Delta Q = 6 \times 1^-2 \times 60\\\\\Delta Q = 3.6 kg \times m/s$

As there is a similar momentum

So,

$\Delta Q = MV\\\\3.6 = 10^-2V\\\\V = 360 m/s$

Hence, the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is 360 m/s

You have just landed your first job as a structural engineer and you have been asked to design a regional airport for small plan

lidiya [134]

Answer: $197.40\ m$

Explanation:

Given

final velocity at takeoff $v=28.1\ m/s$

Acceleration of the plane can be $a=2\ m/s^2$

Initial velocity is zero for the plane i.e. $u=0$

Using the equation of motion

$\Rightarrow v^2-u^2=2as\quad [\text{s=displacement}]\\\text{Insert the values}\\\Rightarrow (28.1)^2-0=2\times 2\times s\\\\\Rightarrow s=\dfrac{789.61}{4}\\\\\Rightarrow s=197.40\ m$
