A) the value of tanx
B) the speed of the particle as it passes over the wall
C) the horizontal distance of the particle from the wall when it again reaches the level of O. Take g as 10 m s^-2
An airplane must reach a speed of 322 km/h to take off. If the runway is 500 m long, what is the minimum value of the acceleration that will allow the airplane to take off successfully?
An inelastic uniform sphere of radius a is sliding without rotation on a smooth horizontal plane when it impinges on a thin horizontal rod at right angles to its direction of motion and at a height b from the plane. Show that it will just roll over the rod if its velocity be
Two boxes connected by a light horizontal rope are on a horizontal surface. The coefficient of kinetic friction between each box and the surface is 0.30. Box B has a mass of 5kg and box A has a mass of mkg. A force F with a magnitude of 40N and direction of 53.1° above the horizontal is applied on the 5kg box, and both boxes move to the right with an acceleration of 1.5m/s^2.
(A) what is the tension on the rope that connects the two boxes?
(B) what is the mass of the other box?
when a stone has fallen a distance x after being dropped from the top of a tower another stone is dropped from point y below the top op the tower, if both reach the ground at the same time prove that height of the tower is (x+y)2/4x

b. Calculate the numerical value of I in A.
c. Express the terminal voltage ΔV of the battery in terms of I and R.
d.Calculate the numerical value of ΔV in V.
