A shell travelling with a horizontal velocity of 100 m/sec explodes and splits into two parts, one of mass 10 kg and the other of 15 kg. The 15 kg mass drops vertically downward with initial velocity of 100 m/sec and the 10 kg mass begins to travel at an angle to the horizontal of tan”1 x, where x is

‘ω’ rad/sec is the angular velocity of a crank whose radius is ‘r’. If it makes θ° with inner dead centre and obliquity of the connecting rod ‘l’ is ‘ϕ’, the velocity v of the piston, is given by the equation

ω (l sin ϕ + r cos ϕ tan θ)

ω² (l sin ϕ + r cos φ tan θ)

ω² (l cos ϕ + r sin ϕ tan θ)

ω² (l sin ϕ - r cos θ tan ϕ)

ω (l sin ϕ + r cos ϕ tan θ)

ω² (l sin ϕ + r cos φ tan θ)

ω² (l cos ϕ + r sin ϕ tan θ)

ω² (l sin ϕ - r cos θ tan ϕ)
