F = ma F=m* [ (v-v 0 )/ (t-t 0) Since the car initially at rest, v 0 = 0 and t 0 = 0 Therefore, Substituting all values, Let’s convert the velocity into speed in metre per second. 1km = 1000m 1hour= 3600sec v=60* (1000/3600) v=60000/3600 v = 16.6
WebVelocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt. Created by Sal Khan. Sort by: Top Voted WebSolution: Using Formula for Speed, Speed = Distance ÷ Time Speed = 3600 ÷ (30 × 60) = 2 Answer: Your speed if you travel 3600m in 30 minutes is 2 m/s.
