. You are driving north on l-5. Then, without changing speed, you round a curve and drive east on l-405. 1. Does your velocity change? Explain. 2. Do you accelerate? Explain. . Give an example of an instance when your speed could be zero, while your acceleration is non- zero. . Hiba, with a reaction time of 0.20 seconds, rides her bike at a constant speed of 6.0 m/s. When a ball suddenly rolls in front of her, Hiba applies her brakes as quickly as she can (0.20 seconds later). 1. How far does Hiba travel before she actually applies the brakes? (answer: 1.2 m) 2. If the acceleration of her brakes is 8.00 m/sZ, how far does she roll before coming to a stop? (answer: ~2.3 m) 3. What total distance does Hiba travel from when the ball rolls in front of her bike to when she comes to a complete stop? (answer: ~3.5 m) . Calculate the acceleration on the 8 kg box below: (answer; 0.5 m/sz) 5N 2N '_-=)> 7N . Consider a 40.0kg crate that is pulled sideways with a net force of 200N. Find the acceleration of the crate. (answer: 5.0m/32)
