Question

The
velocity of
object change
from
v1= 10 i + 4j + 2k
v2=4 + 25 + 3R
in 5
seconds.
find the
magnitude of
average
acceleration
​

Answer 1

❤ ƓƠƠƊ ƝƖƓӇƬ ❤

Acceleration = (v₂ - v₁) / T

= (4i + 2j + 3k - 10i - 4j - 2k) / 5

= (-6i - 2j + k) / 5

= -1.2i - 0.4j + 0.2k

Magnitude = √(1.2² + 0.4² + 0.2²) = 1.28 m/s²
