Question

The driver of a car moving at 96.0 km/h receives a text message on his cellphone. If

it takes him 6.7 seconds to read and respond to the message. How many meters
does he drive during this time?

Answer 1

179 m

Step-by-step explanation:

Given:

v₀ = 96.0 km/h × (1000 m/km) × (1 h / 3600 s) = 26.67 m/s

a = 0 m/s²

t = 6.7 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (26.67 m/s) (6.7 s) + ½ (0 m/s²) (6.7 s)²

Δx = 179 m
