A stone is projected at an angle 60 degrees to the horizontal with the velocity of 30m/s. Calculate the highest point reached, the range, the time taken for flight and the height of the stone at the instant that the path makes an angle 30 degrees with the horizontal
A man stands on the edge of a cliff and throws a stone vertically upwards with an initial speed, u. He then throws another stone vertically downwards with the same vertical velocity. Which stone, if either, has the greater velocity when it hits the ground
A projectile is fired south at an angle of 30 degrees to the horizontal on latitude 60 degrees. Find the derivation to east or west. The initial velocity is 10m/s
The period of a certain pendulum is 2.0 seconds and the mass of the pendulum Bob is 50g. The Bob is pulled aside through a horizontal distance of 8cm and then released. Find the displacement and kinetic energy of the Bob 0.7seconds after release
What is the average velocity of a man who ran a distance of 3km at a
velocity of 7.5 m/s, and the walked 1km at a velocity of 0.8 m/s?
Two trucks A and B, each
traveling at 40 km/hr, move
towards each other. At the
instance when the two trucks are
at a distance 50 km from one
another, a car moving at 60 lm/hr
overtakes A. How far behind the
car is A at the point when the car
meets B?

An object of mass 3kg is acted upon by two horizontal forces of 6N and 3N In the opposite directions Calculate the acceleration produced by the system.
A sled weighing 100 lb. reaches the foot of a hill with a speed of 40 ft/s. The coefficient of kinetic friction between the sled and the horizontal surface of the ice at the foot of the hill is 0.030. How far will the sled travel on ice?
