Question

A little car has a maximum acceleration of 2.57 m/s2. What is the new maximum acceleration of the little car if it tows another car that has the same mass?

Answer 1

Answer:

In order to solve this we can use Newton's Second law (F = ma)

For the first part we can write the above equation like below,

F1 = M1 x 2.57 ------------------------------(1)

For the Second part we can write the above equation like below,

F1 = 2M1 x a -------------------------------(2)

By equaling the above two equations,

M1 x 2.57 = 2M1 x a

a = 2.57/2

= 1.285 m/s^2
