A child (mass m) sits on a car seat which is accelerating horizontally at 0.50g (where g is the acceleration of free fall). What is the magnitude of the total force F exerted by the seat on the child?​

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

The image below shows numerous volcanic mountains in the pacific northwest. what is the most likely cause of the volcanic and earthquake activity in this region?

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
