Answer:
y = 4 Sin (2πt)
Explanation:
Amplitude, A = 4
frequency, f = 1
Wave function is given by
y = A sinωt
where, ω is angular frequency
ω = 2 π f = 2 π x 1 = 2π
So, the desired wave function
y = 4 Sin (2πt)
Answer:
<h3>The answer is 2 s</h3>
Explanation:
The time of flight can be found by using the formula

d is the distance covered
v is the velocity
From the question we have

We have the final answer as
<h3>2 s</h3>
Hope this helps you
Explanation:
Velocity ratio of simple machine is the ratio of distance travelled by effort to the distance travelled by load in the machine. The efficiency of a simple machine is defined as the ratio of useful work done by machine (output work) to the total work put into the machine (input work).

Answer:
1.28 s
Explanation:
Given:
Δy = 8 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
(8 m) = (0 m/s) t + ½ (9.8 m/s²) t²
t = 1.28 s
