Answer: Tom drove 60 km/hr fast
Speed = Distance traveled / time taken
Explanation:
Given that:
Distance traveled by Tom = 60 km
Time taken by Tom = 1 hour
Speed = ?
Since speed is obtained by dividing distance traveled by the time taken, hence the formula to use is as follows:
speed = distance / time
Speed = 60 km / 1 hour
Speed = 60 km/hr
Thus, Tom had been driving 60 km/hr fast, using the formula "speed = distance / time"
Answer:
I'm pretty sure that the answer is A
Answer:
-2 m/s²
8.7 m/s
Explanation:
Using Newton's second law, the sum of forces in the x direction:
∑F = ma
-120 N = (60 kg) a
a = -2 m/s²
Given:
Δx = 6.0 m
v₀ = 10 m/s
a = -2 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (10 m/s)² + 2 (-2 m/s²) (6.0 m)
v = 8.7 m/s
