Final answer:
Using the formula for final velocity v = u + at, with the given initial velocity, acceleration, and time values, Angelo's new velocity is calculated to be approximately 2.97 m/s west.
Step-by-step explanation:
To find Angelo's new velocity, we will apply the formula for final velocity which takes into account the initial velocity, acceleration, and time. The formula is v = u + at, where:
- v is the final velocity,
- u is the initial velocity,
- a is the acceleration,
- t is the time.
Given that Angelo's initial velocity (u) is 1.05 m/s west, the acceleration (a) is 0.74 m/s² west, and the time (t) is 2.6 s, we can substitute these values into the formula to calculate the new velocity:
v = 1.05 m/s + (0.74 m/s² * 2.6 s)
v = 1.05 m/s + 1.924 m/s
v = 2.974 m/s
Approximating to two decimal places, Angelo's new velocity is 2.97 m/s west, which is closest to answer choice (A) 2.92 m/s west, assuming that the answer choices may contain a slight rounding difference.
