Supplies are to be sent across the hill using a canon that can hurl packets at a speed of 125 m/s over the hill. (f) how does θ in (v) compare with that for u = 0 (i.e.45°)?
Show in the diagram, direction of velocity and acceleration at points A, B and C. A ball is thrown from a roof top at an angle of 45° above the horizontal. Viscosity, Stokes' law, terminal velocity, streamline and turbulent flow, critical velocity, Bernoulli's theorem and its applications.
(ii) We can take x-direction along the plane and y-direction perpendicular to the plane. Along with the NCERT Solutions for Class 11 Physics, Toppr provides its students with hundreds of videos, thousands of practice questions and other such invaluable materials. A boy travelling in an open car moving on a levelled road with constant speed tosses a ball vertically up in the air and catches it back. This gives trajectory as a parabola as you have studied. Excellent site ! We have rectified the link. These questions are based on CBSE previous year Physics Exam question papers of Class 11. The canon is located at a distance of 800m from the foot of hill and can be moved on the ground at a speed of 2 m/s; so that its distance from the hill can be adjusted. A hill is 500 m high.
