Answer:
Explanation:
From Newton's 2nd Law, we have . We can use this to find the acceleration of object after 20 N (force) is applied to the 10 kg object.
Substituting given values, we have:
Now that we have acceleration, we can find the final velocity of object (after 0.5 seconds) using the following kinematics equation:
, where is final velocity, is initial velocity, is acceleration, and is time.
Solving for final velocity:
The momentum of an object is given as . Since we've found the final velocity and mass stays constant, we have:
Answer:
Explanation:
18 kW = 18000 J /s
60% of 18kW = 10800 J/s
Latent heat of evaporation of water
= 2260 x 10³ J / kg
kg of water being evaporated per second
= 10800 / 2260 x 10³ kg /s
= 4.7787 x 10⁻³ kg / s
= 4.78 gm / s .
Answer:
An East Coast location was desirable because any rockets leaving Earth's surface and traveling eastward get a boost from the Earth's spin. A West Coast location would either send rockets over populated areas or have to contend with launching against the direction of the spin.
Explanation:
I do not have a answer for What is the launch window. Sorry.
Explanation:
The potential energy is stronger at the start of the bounce and when it is near the end bounce the balls accelerated rate will be lower because the force has decreased . Also I love your profile picture miraculous rocks !
