Answer:
The answer is below
Explanation:
a) The vertical displacement = Δy = 21.5 m - 1.5 m = 20 m
The horizontal displacement = Δx = 69 m wide
Using the formula:
Also:
b)The car is moving at a constant speed in the horizontal direction, hence the initial velocity = final velocity
Answer:
Explanation:
Given
Potential Energy is given by
And Force is given by
Particle will be at equilibrium when Potential Energy is either minimum or maximum
i.e.
So angular Frequency of small oscillation is given by
for
we get
Speed = Distance/ Time
Speed = 400 / 4
Speed = 100 km/hr.
100 km per hour.
