An object in a simulation accelerates from a rest speed of 4 meters per second in 2 seconds. it then accelerates linearly for the next 3 seconds until it reaches 10 meters per second. the object remains at that speed (acceleration=0) for 3 seconds and then de-accelerates linearly until it comes to rest 2 seconds later. which graph demonstrates the speed of the object for those 10 seconds?

Ihave these questions i need to find the acceleration, explain how to do them, don't have to explain all xd 1. change in speed = 14 m/s; time taken = 2 seconds. calculate the acceleration. 2. a car accelerates from rest (zero speed) up to a speed of 30 m/s in 12 seconds. calculate the acceleration. 3. a cyclist in the tour de france accelerates down a hill from 22 m/s to a speed of 37 m/s. this acceleration takes him 2 seconds. calculate the acceleration. 4. a rocket launching in the ukraine accelerates upwards from rest to a speed of 12 km/s in 8 seconds. calculate the acceleration. 5. a cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. what is his acceleration ? is this acceleration higher than that of a car which accelerates from 0 to 30 m/s in 8 seconds? 6. a car advertisement states that a certain car can accelerate from rest to 70 km/h in 7 seconds. find the car’s average acceleration. 7. a lizard accelerates from 2 m/s to 10 m/s in 4 seconds. what is the lizard’s average acceleration? 8. if a ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 50 m/s2 for 3 seconds, what will its final velocity be?
