Please help me on Law of Acceleration - Physics?

A vehicle is accelerating at a rate of 1.20 m/s^2. if the net force is tripled and the mass is halved, what is the new acceleration of the vehicle?

A 1,800.00-kg car uniformly accelerates for 12.50s from rest. during this time the car travels 145 m, north. what is the net force acting on the car during this acceleration?

A 3,500-kg truck accelerates uniformly from 15.00 m/s east to 35.00m/s east. during this acceleration, the truck travels 187.00m. What is the net force acting on the car during this acceleration?

Ahorizontal force of 30.00 N is applied to a 60.00kg grocery cart on a level floor.
a.) how far will it move in 5.00s, starting from rest? ignore friction
b.)how far will it move in 5.00s if 20.00N of groceries are added to the grocery cart first?
