In deep space (no gravity), the bolt (arrow)
of a crossbow accelerates at 201 m/s2 and
attains a speed of 106 m/s when it leaves the
bow.
For how long is it accelerated?
Answer in units of s.

Respuesta :

t  = 0.527 s

It accelerates for 0.527 s.

Explanation:

We use the formula:

v = u+at

Given:

v = 106 m/s

u = 0 (since no gravity)

[tex]a=201 \mathrm{m} / \mathrm{s}^{2}[/tex]

So applying the formula,

v = u+at

106 = 0 + 201t

t     = 106/201

t     = 0.527 s
