Determine the launch speed of a horizontally launched projectile that lands 26.3m from the base of a 19.3m high cliff
mote1985 [20]

The launch speed of a horizontally launched projectile is 13.28 m/s.

<h3>Time of motion of the projectile</h3>

The time of motion is calculated as follows;

t = √(2h / g)

where;

  • h is height of the cliff
  • g is acceleration due to gravity

t = √(2 x 19.3 / 9.8)

t = 1.98 s

<h3>Launch speed of the projectile</h3>

X = Vxt

Vx = X/t

Vx = (26.3)/(1.98)

Vx = 13.28 m/s

Thus, the launch speed of a horizontally launched projectile is 13.28 m/s.

A machine part rotates at an angular speed of 0.76 rad/s; its speed is then increased to 2.96 rad/s using an angular acceleratio
son4ous [18]

Answer:

θ = 4.092 °

Explanation:

Given that

Initial Angular speed ,ωi = 0.76 rad/s

Final angular speed ,ωf= 2.96 rad/s

The angular acceleration ,α = 1 rad/s²

We know that

ωf² = ωi ²+ 2 α θ

θ=Angle rotates

2.96² = 0.76²+ 2 x 1 x θ

\theta=\dfrac{2.96^2-0.76^2}{2}\ degrees\\\theta=4.092\ degrees\\

Therefore the angle rotates by machine part will be 4.092 degrees.

θ = 4.092 °
