gAn Olympic diver is on a diving platform 5.40 m above the water. To start her dive, she runs off of the platform with a speed o

f 1.17 m/s in the horizontal direction. What is the diver's speed, in m/s, just before she enters the water

Answer:

The diver's speed, in m/s, just before she enters the water = 10.19 m/s

Explanation:

Assuming the horizontal velocity of the diver remains constant by neglecting the air resistance.

V^2 = U^2 + 2as

Where, V^2 = the diver's final velocity before impact with the water

            U^2 = Initial diver's velocity as she leaves the diving platform

                a = acceleration due to gravity

                s = the displacement

V =  √U^2 + √2as

= √(5.40 m/s)^2 + √2(9.81 m/s/s) (1.17 m)  

= √ 29.16 + √ 22.9554

=  5.40 + 4.79

= 10.19 m/s

3. Which one of these has the most inertia?
Arte-miy333 [17]

b. A Boeing 747 airplane

Explanation:

The Boeing 747 airplane will have the most inertia of all. Inertia is the tendency of an object to remain at rest or uniform motion.

  • Newton's first law of motion is also regarded as the law of inertia.
  • It states that "an object will remain at rest or uniform motion motion unless acted upon by an external force".
  • A body that has a large mass will be more resistant to any external force that acts on it.
  • The Boeing 747 has the most mass of all and will have the most inertia.

Projectile A is launched horizontally at a speed of 20. Meters per second from the top of a cliff and strikes a level surface be
miv72 [106K]

consider the motion of projectile A in vertical direction :

v₀ = initial velocity of projectile A in vertical direction = 0 m/s         (since the projectile was launched horizontally)

a = acceleration of the projectile = g = acceleration due to gravity = 9.8 m/s²

t = time of travel for projectile A = 3.0 seconds

Y = vertical displacement of projectile A = height of the cliff = h = ?

using the kinematics equation along the vertical direction as

Y = v₀ t + (0.5) a t²

h = (0) (3.0) + (0.5) (9.8) (3.0)²

h = 44.1 m
