Two runners start a race. After 2 seconds, they both have the same velocity. If they both started at the same time, how do their average accelerations compare?
2 answers:
let each runner starts from rest
v₀ = initial velocity of each runner = 0 m/s
t = time of travel = 2 sec =
a = average acceleration
average acceleration is given as
a = (v - v₀)/t
inserting the values
a = (v - 0)/t
a = v/t
since each runner gains equal amount of speed in given time interval of "t". hence the average acceleration of each runner is same.

Distance, such that displacement over time is taken into account doesn't change regardless of the length in x meters or mass in kg So the force will remain constant given 16 units
Answer:
16.2 s
Explanation:
Given:
Δx = 525 m
v₀ = 0 m/s
a = 4.00 m/s²
Find: t
Δx = v₀ t + ½ at²
525 m = (0 m/s) t + ½ (4.00 m/s²) t²
t = 16.2 s
