I need help I'm struggling with this page

ACTIVITY 7 Shown below is the formula for average acceleration. Av Acceleration = final velocity -initial velocity t time Solve the following questions. Show your work in the space provided on next page. 1. A hamster notices food and increases the speed of its wheel from 0.1m/s to 0.3 m/ s in 30 seconds. What is the average acceleration of this hamster? Round your answer to the nearest thousandth. 2. A car moving at 45 m/s makes a sudden stop after seeing a squirrel on the road. It takes the car 10 seconds to make a complete stop. What is the acceleration of the car? Show your calculation. 3. If the car mentioned above was moving at 60 m/s instead and slowed down at the same rate, how much longer would he have taken to get to the complete stop? Round to the nearest second
