Moderate# Compare Two Objects

MVCALC-V11NL3

Two objects move along the same smooth curve so that the velocity of the first object is given by the function ${\bf v}(t)$, and the velocity of the second object is given by the function $2{\bf v}(t)$.

The two objects start at the same point.

If the tangential and normal components of acceleration in a fixed moment $t$ are denoted by $a( T_1)$ and $a( N_1)$ for the first object, and by $a(T_2)$ and $a(N_2)$ for the second object, which of the following five statements is **NOT** always true?
