Question

A modern car can develop an acceleration four times greater than an antique car like “Lanchester 1800”. If they accelerate over the same distance, what would be the velocity of the modern car compared to the antique car? Select one:

a. Twice as much

b. Half as much

c. Four times as much

d. The same

e. One quarter as much

Answer 1

Answer:

Explanation:

A, twice as much.

with our 5 properties, we do not need time. finding an equation without time would be: v^2= 2a (deltax). plugging in 4 in front of a, we are multiplying the whole side by 4, therefore we have to multiple the other side by four as well. you would think it would be 4 but no because you have to square 4 as well. therefore the answer would be twice as much.
