Answer:
Explanation:
From the equation of Newton's laws of motion
v = u + at where v is final velocity , u is initial velocity and t is time.
150 = 0 + a x 3
a = 50 m / s ²
s = ut + 1/2 at² ; s is distance travelled
s = 50 x 3 + .5 x 50 x 3²
= 150 + 225
= 375 m .
Hi there!
The period is given by:
T = Period (sec)
w = angular frequency (rad/sec)
According to the equation for SHM in terms of position:
y(t) = Asin(ωt + φ)
A = Amplitude (m)
ω = angular frequency (rad/sec)
t = time (sec)
φ = phase angle
In this instance, the angular frequency is given as 18π.
Plug this value into the equation for T:
Tango landed in a site of lower temperature while Foxtrot landed in a site of higher temperature.
<h3>Effect of temperature on speed of sound</h3>
Speed of sound increases with increase in temperature because air molecules acquires more kinetic energy which increases their rate of vibration.
From the information, the speed of sound picked by Foxtrot (258 m/s) is greater than the speed of sound picked by Tango (240 m/s).
We can conclude that, Tango landed in a site of lower temperature while Foxtrot landed in a site of higher temperature.

Answer:
Kinetic energy at maximum height is zero.
Explanation:
At maximum height, the velocity is zero. Thus, the kinetic energy is also zero. This can further be seen as illustrated below:
Let the mass of the object be = m
Velocity (v) at maximum height = 0 m/s
Kinetic energy (KE) at maximum height =?
KE = ½mv²
KE = ½ × m × 0²
KE = ½ × m × 0
KE = 0
From the illustration above, we can see that the kinetic energy at maximum height is zero.
