How much force is needed to accelerate a 1000kg car at a rate of 3m/s2?

According to Newton (2nd law),   Force = (mass) x (acceleration)

Substitute what we know :           Force = (1,000 kg) x (3 m/s²)

Do the arithmetic:                        Force = 3,000 kg-m/s²  =  3,000 newtons

“when two plates carrying continents collide, the continental crust buckles and rocks pile up, creating towering mountain ranges. when an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. this process is called subduction. “ i found this on google i hope it
