A certain force gives mass (m1) an acceleration of 8 m/s^2 and a mass(m2) an acceleration of 24 m/s^2.what acceleration would it give the two when they are fastened together?? pls don't ignore I need the answer pleaseee

What is the magnitude of the acceleration vector which causes a particle to move from velocity −5i−2j m/s to −6i+ 7j m/s in 8 seconds. answer in m/s.

Consider a system with two masses that are moving away from each other. why will the kinetic energy differ if the frame of reference is a stationary observer or one of the masses?

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
