true because they wont be able to comperes hard enough to set off little nuclear explosins
Impulse<span> is the change of momentum of an object when the object is acted upon by a force for an interval of time. It is simply calculated by the expression:
</span>
Impulse = F(change in time)
Impulse = 60(2)
Impulse = 120 Ns
Hope this answers the question. Have a nice day.
Answer:
65.73N
Explanation:
The frictional force is a force that opposes the motion of an object on a flat surface or an inclined surface.
It is always acting up an incline plane .
Since the pipe will tend to roll up the plane, then both the impending force P also known as frictional force and the moving force Fm both will be acting up the plane.
The net force acting up the plane is
Fnet = P + Fm... (1)
The force perpendicular to the plane known as the normal reaction R must be equal to the force acting along the ramp in other to keep the body in equilibrium i.e R = Fnet
If R = W = mgcos (theta)
and Fm = mgsin(theta)
Then mgcos theta = Fnet
mgcos (theta) = P+Fm
mgcos (theta) = P+mgsin(theta)
P = mgcos (theta) - mgsin(theta)... (2)
Given mass = 10kg
g = 9.81m/s
We can get theta from the formula;
µ = Ff/R = wsin theta/wcos theta
µ = sin theta/cos theta
µ = tan(theta)
0.3 = tan (theta)
theta = arctan0.3
theta = 16.7°
P = 10(9.81)cos16.7° - 10(9.81)sin16.7°
P = 98.1(cos16.7°-sin16.7°)
P = 98.1(0.67)
P = 65.73N
The minimum force P required to cause impending motion is 65.73N
