A space craft of mass 2000 kg moving with a velocity of 600m/s suddenly explodes into two pieces. One piece of mass 500 kg is left stationary. The velocity of the other part must be

If at the highest point of parabolic path kinetic energy is equal to potential energy, the angle of projection would be:

A man and a cart move towards each other. The man weighs 64 kg and the cart 32 kg. The velocity of the man is 5.4 km/hr and that of the cart is 1.8km/hr. When the man approaches the cart, he jumps on to it. The velocity of the cart carrying the man will be:

A body projected obliquely with velocity 19.6 m/s has its kinetic energy at the maximum height equal to 3 times its potential energy. Since projection from the ground, its height from ground after 1s is:

(h = maximum height, take g=9.8 m/s²)

A curve is drawn expressing the kinetic energy of a particle as a function of the distance traversed (on X-axis). The slope of this curve represents the instantaneous:

A bullet is fired from a gun, the force on the bullet is given by F=600−2×10⁵t where F is in newton and t in second. The force on the bullet becomes zero as soon as it leaves the barrel. What is the average impulse imparted to the bullet?

A bullet fired into a fixed target looses half of its velocity in penetrating 15cm. Before coming to rest, it can penetrate a further distance of:

A man carries a load of 50kg through a height of 40m in 25seconds. If the power of the man is 1568W, his mass is:

A motor pump set of efficiency 80%, lifts 800 litres of water in 19.6 seconds over a head of 20m. Its input power is (Take g=9.8 m/s²):

A tank of size 10m×10m×10m is full of water and built on the ground. If g=10 ms⁻², the potential energy of the water in the tank is:
