Can some one tell me what this formula or equation is?
-> . 2. ->
∆r=½a ∆t. +v ∆t
0
the -> is an vector i believe and the 0 is what was under the v. also the 2 is a exponent. me, also you! : 3

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.

Iwould say the answer is d

Special care would be an answer
