5. ssm How long does it take a plane, traveling at a constant speed of 110 m/s, to fl y once around a circle whose radius is 2850 m

162.71 s

Explanation:

Applying,

v = 2πr/t Equation 1

Where v = Velocity of the plane, r = radius of the plane, t = time, π = pie.

make t the subject of the equation

t = 2πr/v Equation 2

From the question,

Given: r = 2850 m, v = 110 m/s

Constant: π = 3.14

Substitute these values into equation 2

t = (2×3.14×2850)/(110)

t = 17898/110

t = 162.71 s

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
