Two students, sitting on frictionless carts, push against each other. Both are initially at rest and the mass of student 1 and t
1 answer:
Answer:
v₂ = v/1.5 = 0.667 v
Explanation:
We will apply the conservation of momentum for this problem, defining a system that includes both students and their carts; the forces during contact are considered internal, ensuring momentum is conserved.
Initial momentum before the push
p₀ = 0
Final momentum after the push yields
= m₁ v₁ + m₂ v₂
0 = m₁ v₁ + m₂ v₂
Substituting yields
M (-v) = -1.5M v₂v₂ = v / 1.5
v₂ = 0.667 v

Answer:
Explanation:
Provided data:
The motorist's initial speed is 20 m/s.
The distance to the traffic light is 200 m.
The duration of the red light is 15 s.
It takes 1 s for the driver to apply the brakes.
Distance covered during this response time
d = s x t
d = 20 x 1 = 20 m
The time to arrive at the red light after factoring in the reaction time is 15 - 1 = 14 s.
The remaining distance to cover within this time is 200 - 20 = 180 m.
To determine the motorist's speed upon reaching the red light, employ the equation of motion
Utilizing the equations of motion to ascertain the velocity:
The speed of the motorist as she reaches the red light is 5.72 m/s.
