I the total acceleration of an object is 60 m/s2 and its rudial neceleration is 30 m/s due sousth what is tarigential acceleration of the object and the direction of the object? A car moving with a constant acceleration that started from rest goes over a bump, which has a magnitude of the total acceleration of the car? 3.

Answer 1

1.

$T=\frac {2\pi r}{v}=\frac {2\cdot \pi\cdot 5}{300}\: s=0.104\: s$

2.

$a=\sqrt {a_r^2+a_t^2}$

$60=\sqrt {30^2+a_t^2}$

$a_t=51.96\: m/s^2$ (East)

3.

$v=\frac {2\pi r}{T}=\frac {2\pi \cdot 100}{6}\: m/s=104.7\: m/s$

$a_c=\frac {v^2}{r}=\frac {104.7^2}{100}\: m/s^2=109.62\: m/s^2$
