A1050 kg automobile is at rest at a traffic signal. at the instant the light turns green, the automobile starts to move with a constant acceleration of 3.3 m/s2. at the same instant a 2350 kg truck, traveling at a constant speed of 8.6 m/s, overtakes and passes the automobile.
(a) how far is the center of mass of the automobile-truck system from the traffic light at t = 2.1 s?
(b) what is the speed of the center of mass of the automobile-truck system then?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied. true or false

Could someone . i have tried to solve myself but my calculation is off

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
