s=16
u=6.94
v=0
a=a
v^2=u^2+2as
(v^2-u^2)/2s = a =1.5ms^-2
Answer:
610 meters.
Explanation:
Because Jim released the accelerator, the truck started to slow down, so the friction force will eventually stop the truck.
the kinetic energy of the truck just after Jim released the pedal is:
![E_k=\frac{1}{2}*m*v^2\\E_k=\frac{1}{2}*2268*(22)^2=548856J](https://tex.z-dn.net/?f=E_k%3D%5Cfrac%7B1%7D%7B2%7D%2Am%2Av%5E2%5C%5CE_k%3D%5Cfrac%7B1%7D%7B2%7D%2A2268%2A%2822%29%5E2%3D548856J)
The work done by the friction force is given by:
![W_f=F_s*d\\\\d=\frac{548856J}{900N}\\\\d=610m](https://tex.z-dn.net/?f=W_f%3DF_s%2Ad%5C%5C%5C%5Cd%3D%5Cfrac%7B548856J%7D%7B900N%7D%5C%5C%5C%5Cd%3D610m)
Answer:
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. ... In electric circuits the charge carriers are often electrons moving through a wire.
To find the answer, take 55 and divide it by 1.85 to get the thickness of one card. In this case the answer would be 29.72973 cm. each.
Explanation:
<u>Mass of car</u> = 137.5 kg
<u>Acceleration</u> = v - u / t = 26 - 0 / 6 = 4.33 m/sec^2
Force = m * a = 137.5 * 4.33 = 595.3 N
