Which Formula One team, founded in 1963 by a New Zealander, were first to design a car using a carbon fibre monocoque?
A simple pendulum with length l and bob of mass m execute simple harmonic motion of small amplitude A. What would be the maximum tension in the string?
The tension in the string at any position is given by the formula:
T = m x g x cos(a) + m x (v)Exp 2 / L
T = tension in the string
m= mass of the bob
a = the angle
v= velocity of the mass
L = lenght of the string
The maximum tension is achieved when a = 0, then cos (0) =1 and v = maximum velocity
A spherical shell of mass m is resting on the rough horizontal plane with a coefficient of friction 0.3 a horizontal force act at a distance of 5r/3 from the baseline where r is the radius of the sphere.
Find work done by friction body has moved by a distance of gm/r from the initial position?

A wooden block of mass m resting on a rough horizontal table is pulled by a force F as shown in figure. If k is the Coefficient of friction between block and table. What will be its acceleration?
A particle moves in a straight line such that the displacement x at any time 't' is given by
x = 6t^2 - t^3 - 3t - 4.
x is in meter and t is in seconds.
