On a two-lane road, car A is travelling with a speed of $36km{h}^{-1}$. Two cars B and C approach car A in opposite directions with a speed of $54km{h}^{-1}$ each. At a certain instant, when the distance AB is equal to AC, both being 1 km, B decides to overtake A before C does. What minimum acceleration of car B is required to avoid an accident ?Solution in Telugu

A boy standing on a stationary lift (open from above) throws a ball upwards with the maximum initial speed he can, equal to $49m{s}^{-1}$. How much time does the ball take to return to his hands ? If the lift starts moving up with a uniform speed of $5m{s}^{-1}$ and the boy again throws the ball up with the maximum speed he can, how long does the ball take to return to his hands ?

State , for each of the following physical quantities , if it is a scalar or a vector : volume , mass , speed , acceleration , density , number of moles , velocity , angular frequency , displacement , angular velocity .

An air chamber of volume V has a neck area of cross section a into which a ball of mass m just fits and can move up and down without any friction (Fig.14.27). Show that when the ball is pressed down a little and released , it executes SHM. Obtain an expression for the time period of oscillations assuming pressure-volume variations of air to be isothermal [see Fig. 14.27].

दो लेन वाली किसी सड़क पर एक कार (A) 36 किमी/घण्टा की चाल से चल रही है। एक-दूसरे की विपरीत दिशाओं में चलती हुई दो कारें B व C जिनमें से प्रत्येक की चाल 54 किमी/घण्टा है कार A तक पहुंचना चाहती है। किसी क्षण जब दूरी AB दूरी AC के बराबर है तथा दोनों 1 किमी है कार B का चालक यह निर्णय करता है कि कार C के कार A तक पहुंचने के पहले ही वह कार A से आगे निकल जाये। किसी दुर्घटना से बचने के लिए कार B का कितना न्यूनतम त्वरण जरूरी है?

दो - लेन वाली किसी सड़क पर कार A, 54 किमी/घण्टा की चाल से चल रही है । एक दूसरे की विपरीत दिशाओं में चलती दों कारें B व C जिनमें से प्रत्येक की चाल 72 किमी/घण्टा है कार A तक पहुँचना चाहती है । किसी क्षण जब दूरी AB दूरी AC के बराबर है तथा दोनों 1 किमी है कार B का चालक यह निर्णय करता है कि कार C के कार A तक पहुँचने के पहले ही वह A कार से आगे निकल जाए । किसी दुर्घटना से बचने के लिए कार B का कितना न्यूनतम त्वरण जरूरी है ?
