1. Homework Statement
- A car of mass 1.4 tonnes (1400 kg) traveling down the highway at 120 km/h has a F air of 1800 N acting against it. What force must be applied by the engine if the car's speed is to increase to 130 km/h in 5.5 s?
- A 786 kg rock is being towed on a frictionless surface by a 45 N force acting north. A second force acts at 32 N west. What is the acceleration of the rock? (Note that the forces are not acting directly opposite to one another.)
