The airplane shown in the figure is to achieve "weightlessness" for a short period of time by flying along a curved path such that it's acceleration components in x direction ax = 0 and in y direction ay = -g. If the velocity of the plane in x - direction Vx = V0 and y-direction Vy=0 at the time t=0 and plane is at point O.
(i) Derive a tangential acceleration of the plane at as function of time t.
(ii) Derive a normal acceleration of the plane as a function of time t
(iii) Calculate the tangential acceleration and the normal acceleration after time t= 5 sec, if V0=980 km/h and g=9.81 m/s2 O.
An object in free fall has an acceleration of 9.80 m/s 2 assuming that there is no air resistance. What is the speed of an object dropped from the top of a tall cliff 3.50 s a
Q Calculate the longest wavelength that can be analysed by a rock salt crystal of spacing d = 2.82 Ao in the first order. Data: d = 2.82 Å = 2.82 × 10-10 m; n = 1 ; λmax = ?
obtain expression for potential at point due to uniformly chargeddisc
An object that is moving in a straight line with speed v covers a distance, d = vt, in time t. Rewrite the equation to find t in terms of d and v. How long does it take a plane tha
Q. What are the characteristics of laser beam? Characteristics of laser The laser beam (a) is monochromatic. (b) is coherent with the waves all exactly in phase with o
During a space launch, an astronaut typically undergoes an acceleration of 3 gs, which means he experiences an acceleration that is three times that of gravity alone. What wou
