I’m sure “save” is the correct answer, as it is the only grammatically correct answer choice. Also, it is easy to save when you know what you’ll have to pay for in the future.
Answer:
2m/s
Explanation:
Given parameters:
Mass of truck = 9000kg
Kinetic energy = 18000J
Unknown:
Speed = ?
Solution:
Kinetic energy is the energy due to the motion of a body;
K.E = 
mv²
So;
m is the mass
v is the speed
2 KE = mv²
2 x 18000 = 9000 x v²
v² = 4
v = 2m/s

shear stress is the measure of the material's resistance to cause "sliding" motion of its layers.
<span>Since the hero has to take a cylindrical piece of metal out, the area which will cause this force is 2*pi*r*l (put r and l in SI units to get answer in Newtons) </span>
<span>so the force required is shear strength into this area (2.60109 * 2 * pi * r * l) </span>
