The students were told that the net applied force from the engine was the same for each vehicle tested. Based on this information, which vehicle had the greatest acceleration?

Vehicle 1

Explanation:

WE know that a=F/m and since F is the same for all vehicles, it means the higher the mass, the lesser the acceleration and the smaller the mass the higher the acceleration. From the table given, vehicle a has the smallest mass, of 1000 Kg hence it yields the highest acceleration

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
