Answer:
50.0 m
Explanation:
First of all, we can find the initial velocity of the ball, using the equation
v = u + at
where
v = 0 is the velocity of the ball at the highest position
u is the initial velocity
is the acceleration of gravity
is the time the ball took to reach the maximum height (half of the time it remained in the air)
Solving for u,
Now we can find the maximum height using the other SUVAT equation:
where d is the maximum height. Solving for d,
Answer:
9.5 km/h
Explanation:
Let v₁ and v₂ be the rates of the cars.
Given that v₂ = v₁ - 20
The first car travels a distance v₁t in t = 5 hrs and the second car travels a distance of v₂t in t = 5 hrs. The total distance between them is 850 km.
So v₁t + v₂t = 850
v₁t + (v₁ - 20)t = 850
v₁t + v₁t - 20t = 850
2v₁t - 20t = 850 at t = 5 hrs
2v₁ × 5 - 20 × 5 = 850
10v₁ - 100 = 850
10v₁ = 850 + 100
10v₁ = 950
v₁ = 950/10 = 9.5 km/h
v₂ = v₁ - 20 = 9.5 - 20 = -10.5 m/s
Since magnitude of v₁ < v₂
The rate of the slower car is 9.5 km/h
