Question

a roller coaster accelerates from an initial velocity of 6.0 m/s to a final velocity of 70 m/s over 4 seconds. whats the acceleration

Answer 1

Answer:

vi=6m/s

vf=70 m/s

t=4s

a=vf-vi/t=16m/s2

Explanation:

Answer 2

The acceleration of the roller coaster is 16 m/s²

The given parameters;

initial velocity of the roller coaster, u = 6 m/s

final velocity of the roller coaster , v = 70 m/s

time of the motion of the roller coaster, t = 4 seconds

The acceleration of the roller coaster is calculated as the change in the velocity per change in time of motion.

$a = \frac{v- u}{t} \\\\a = \frac{70-6.0}{4} \\\\a = 16 \ m/s^2$

Thus, the acceleration of the roller coaster is 16 m/s²
