Two engineers are working to calculate the acceleration of a new car design they submit the following testing procedure to you for approval. step 1) start with the car at rest at the 0m mark. step 2) push down the gas pedal all the way. step 3) allow the car to travel 50m with the gas pedal pressed down. step 4) record the velocity of the car as it crosses the 50m mark. if your company adopts these procedures, will you be able to calculate the acceleration of the new car? (aks 1c1, dok3) question 1 options: no, because you don’t know the initial velocity, and the acceleration can only be calculated if you know the initial velocity. no, because you don’t know the time, and the acceleration can only be calculated if you know the time. yes, because you know the initial velocity, the final velocity, and the distance. yes, because you know the distance, initial velocity, and time.

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?
