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

Yes, the velocity of the arrow when it is released from the bow is the same as the velocity with which it strikes the pendulum, assuming no external forces like air resistance act on it. The arrow's initial velocity is conserved until it impacts the pendulum, meaning that its speed remains constant in the absence of such forces. However, in real-world scenarios, factors like air resistance can slightly reduce its velocity before impact.
it strikes the ground at a velocity of 17.9 ft/s

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 penny falling from the sky is unlikely to kill you due to its low mass and the terminal velocity it reaches during free fall, which is not sufficient to cause lethal injury. While it could potentially cause a minor injury if it strikes someone directly, the risk of a penny causing serious harm is extremely low. In reality, objects falling from great heights are subject to air resistance, which significantly reduces their speed. Thus, a penny is more likely to bounce off rather than cause fatal damage.
Velocity final = vi + at = 49 m/s displacement = vi * t + ½2at² = 122.5 m vi = 0 a ≈ 9.8 t = 5
To calculate the velocity of the ball just before it hits the ground, we can use the equation of motion: velocity = acceleration x time. The acceleration due to gravity is approximately 9.8 m/s^2. Given the time of 3.0 seconds, we can plug these values into the equation to find the velocity. Therefore, the velocity of the ball just before it hits the ground is 29.4 m/s.
Momentum defined as p=mv.. The momentum of the truck depends on its velocity
