Q1. A small car of mass 831 kg is parked at the back, a small truck of mass 1553 kg on a level road. The brakes of both the car and the truck are off so that they are free to roll with negligible friction. An 86 kg woman sitting on the tailgate of the truck shoves the car away by exerting a steady force on the car with her feet. The car accelerates at 0.2 m/s2.

What is the acceleration of the truck?

Answer in units of m/s2

what is the magnitude of force exerted on the car?

Answer in units of N

Q2. Whilst a roofer is working on a roof that slants at 39.0 degrees above the horizontal, he accidentally nudges his 93.0 N toolbox, causing it to start sliding downward, starting from rest. If it starts 4.50 m from the lower edge of the roof, how fast would the toolbox be moving just as it reaches the edge of the roof if the kinetic friction force on it is 18.0 N?
