What is the height of the body dropped from the tower?
[SOLVED] A body is dropped form the top of a tower. It falls through 40 m during the last two seconds of its fall.The height of tower in m is ( g = 10 ms^-2)
What is the total time for covering H height in 5 seconds?
Since a body covers distance in the ratio of 1:3:5:7:9 in equal interval of time if it is dropped from some height. So in 5th second it will cover 9×h/25 that is total time for covering h height is 5 seconds so by equation s=ut+1/2gt^2 we get s=0+1/2×10×5×5=125m. THANKU………….
What is the initial velocity of an object dropped from a building?
Since, the object is dropped from the top of the building, initial velocity is zero, so the value of UT is 0. Hence, the equation can be rewritten as S = 1/2AT². Let the total time taken to drop to the ground be T and the time taken prior to the last second be T-1.
What is the height of the building if T = 5/9?
Since, based on the question, time taken is more than one second. Hence, the second solution where T = 5/9 is not feasible since it is lesser than 1. Hence, the correct solution is T = 5. Hence, the height of the building is 1/2*9.8*5² which comes to 122.5 metres.
How do you calculate free fall distance from height?
Find the free fall distance using the equation s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8 m. If you know the height from which the object is falling, but don’t know the time of fall, you can use this calculator to find it, too!
How far does a particle fall from the height of rest?
But cars usually do not. A particle is dropped under gravity from rest from a height h and it travels a distance of 9h/25 in the last second. What is the height?
How many meters fall in the last second of time?
Since time minus one second equals 2/3 of the total length at time. The last second equalling 1/3 the total length is the same as t-1 equalling 2/3 the total length. And at 4.44948974… seconds the distance is 97.108988… meters leaving 48.55494… meters to fall in the last second.
