Answer: a = 0.647 m/s^2
Explanation:
Acceleration = change in speed / time → a = 22 / 34 → a = .647 m/s^2
Answer:
A. Travel in one direction
Explanation:
light can be reflected and bent but light originally travels in one direction in straight lines
For the given problem, we calculate the required time by
using the formula P = W/t.
P = [(1/2)mv_f^2 – (1/2)mv_i^2]/ t
The car accelerates from 0 -58 mph, so the power engine will
be
P = (1/2) x m x 58^2 / t = 1682 m / t
According to the problem, the engine produces full power so
the time required can be calculated as
420.5 m / 1.40 = 1682 m / t
t = 5.6 seconds
