What is the kinetic energy of an object weighing 65 kg dropped from a height of 40m?
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
How many square meters in 1 thai rai?
1 Thai Rai is approximately equal to 1,600 square meters.
William tell shoots an apple off a tree 20.0 meters away and 4.0 meters high The arrow is released from 1.0 meter above ground The arrow travels for 0.500 seconds. What's the velocity of the arrow?
Interesting! Horizontal distance covered by arrow=20m=Vx(t),put Time=t=0.5s, so Vx=20/.5=40m/s.Now let us consider vertical motion of the arrow,Vertical distance=4m-1m=3m. so Use Second equation of motion now.Y=Vy(t) - gt2/2.Subtituting the values,3=Vy(0.5) - 9.8(.5)2/2. Solving for Vy, we get,Vy= 8.45m/s and Vx=40m/s. nowV2=(Vx2+Vy2) or V2=(8.45)(8.45)+(40)(40)=71.40+1600=1671.40m/s, soV=(1671.40)1/2=40.88m/s. That is the answer!
What is 40m in millimeters?
1 foot = 0.3048 meters Therefore, 40 feet = 40 x 0.3048 meters = 12.192 meters.
A body of mass 5 kg initially at rest is subjected to a force of 20N What is kinetic energy acquired by the body at the end of 10s?
By Newton second law, F=ma; 20=5*a; or a=4m/s/s. initial velocity=0 and time=10s so by first equation of motion V=0+at, so V=4*10=40m/s, so kinetic energy of body=K.E=1/2*m*V2 = 0.5*5*1600=25*160=.....
An apple falls from a tree and reaches the ground in 4 seconds with a velocity of 40m/s. What is the acceleration?
Using the acceleration formula, final acceleration is the final velocity minus the initial velocity over elapsed time. Final velocity you gave as 40m/s, and the initial velocity was zero (the apple was stationary on the tree), so the difference is 40 m/s. Divided by the time you gave, 4 s, this will be 10 m/s²
If a ball is thrown vertically up with the velocity of 40m s what would be its velocity after two seconds?
Ignoring air resistance and using g = 9.81 ms-2, velocity = 20.38 ms-1.
How do you make a complaint to corporate headquarters for Days Inn motels?
a train staring from rest acquires a velocity of 40m/s in 10sec.what is its acceleration
40m×40m×60m =?
To calculate the volume of a rectangular prism, you multiply the length, width, and height. 40m × 40m × 60m = 96, 000 m3.
What is 40M in dollars?
40M refers to 40 million. In dollars, it can be expressed as $40,000,000.
