What is the velocity of a five kilogram rock when it strikes the surface of the moon after falling thirty-five feet?

distance = 1/2 gt^2 wher g is acceleration of gravity on moon = about 5 ft/sec/sec
35 = 2.5t^2
t^2 = 14
t = 3.74 seconds
velocity = at = 5 x 3.74 = 18.7 feet/second
the mass of the rock does not enter into this

How could you know if an object strikes in the wter with greater velocity?
The water would move.
What was falling in 1891?
The Price of Wool. It caused industrial chaos with strikes across the continent.
What is an object that strikes the earth's after falling through the atmosphere?
probably or mostly a meteoroid (scientific answer)
A 0.068-kilogram ball with a velocity of 22.1 meters per second strikes a wall. The wall stops the ball in 0.36 second. What is the average magnitude of the force applied to the ball by the wall?
The law of momentum is Ft = mv; so F = mv/t = 4.17 Newtons
A meteriod with a diameter of 1cm strikes the Moon What will the crater diameter be?
That would depend on several factors; the velocity of the meteoroid, the mass, density and composition of the meteoroid, and the nature of the surface where it strikes.
What is the speed of an object weighing 80 pounds dropped from 7 feet?
it strikes the ground at a velocity of 17.9 ft/s

How much faster will a bullet fly in a vacuum than in atmosphere?
In a vacuum a projectile will maintain its launch speed (muzzle velocity) until gravity pulls it to earth or it strikes something in its path. In absence of gravity it will maintain straight-line flight and velocity until it strikes something. Atmosphere creates drag which slows bullets dramatically.
A child drops a ball from a window. The ball strikes the ground in 3.0 seconds. What is the velocity of the ball the instant before it hits the ground?

When a golf club strikes a golf ball the force exerted by the ball on the club depends on?
the mass of the ball and club and the velocity of the club
A marble dropped from a bridge strikes the water in 5 seconds. What is the speed with which it strikes and the height of the bridge?
Velocity final = vi + at = 49 m/s displacement = vi * t + ½2at² = 122.5 m vi = 0 a ≈ 9.8 t = 5
What is the momentum of a 500 kg truck before it strikes a 300 kg parked car?
Momentum defined as p=mv.. The momentum of the truck depends on its velocity
