Acar of mass 1500kg is towing a trailer if mass 1100kg alonf a level road. the acceleration of the car is 1.30m/s. ignoring friction and air resistance, what is the driving force on the car? a 1430 nb 1950 nc 2000 nd 3380 n

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

If a textbook weighs 37.2 n on venus, and the book has a mass of 4.4 kg, what is the strength of gravity on venus? 8.9 m/s28.9 m/si don't have enough information,9.8 m/s2

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
