Explanation:
Answer:
a) The jogger's acceleration is 1.5 m/s²
b) The car's acceleration is also 1.5 m/s²
c) Yes, the car covers a distance 76 m greater than the jogger.
Explanation:
a) Acceleration is the change in velocity over a given time interval:
a = (final velocity - initial velocity) / time
For the jogger:
a = (3.0 m/s - 0 m/s) / 2.0 s = 1.5 m/s²
b) For the car:
a = (41.0 m/s - 38.0 m/s) / 2.0 s = 1.5 m/s²
c) To find how far the car has traveled after 2 seconds, use the formula for position under acceleration along a straight path:
x = x₀ + v₀ t + ½ a t²
where
x = position at time t
x₀ = initial position
v₀ = initial velocity
t = elapsed time
a = acceleration
Assuming x₀ = 0 (origin at car's starting point):
x = 38.0 m/s × 2 s + ½ × 1.5 m/s² × (2.0 s)²
x = 79 m
Similarly, position of the jogger after 2 seconds is:
x = 0 m/s × 2 s + ½ × 1.5 m/s² × (2.0 s)² = 3 m
The difference traveled by the car compared to the jogger is 79 m - 3 m = 76 m
