1. A car starts from rest and accelerates at a constant rate to 80km/h in 6s in positive direction. What is the acceleration? 2. After how long will the car speed be 120km/h if it keep accelerating at the same rate as in 1.? 3.After the car reached speed...

4.The brakes are applied at the end of the 100s and the car comes to a stop within 20m, slowing down at a constant rate. What is acceleration? 5.Now the car turns back and its speed increases at 5m/s^2 for 7s. What is its speed at the end of 7th second? W...

6.At the end of the 7th second the brakes are applied and the car slows down at a constant rate till it comes to rest in 5s. What is the acceleration? 7.Draw the v vs.t graph 8.find the final displacement: a)by using the graph b)by algebraic calculations...

Important then very much go beat clara

Wow what rubbish
