Two projectiles P1 and P2 thrown with speed in the ratio $$\sqrt3$$ : $$\sqrt2$$, attain the same height during their motion. If P2 is thrown at an angle of 60$$^\circ$$ with the horizontal, the angle of projection of P1 with horizontal will be :
A small toy starts moving from the position of rest under a constant acceleration. If it travels a distance of 10m in t s, the distance travelled by the toy in the next t s will be :
A person can throw a ball upto a maximum range of 100 m. How high above the ground he can throw the same ball?
Two balls A and B are placed at the top of 180 m tall tower. Ball A is released from the top at t = 0 s. Ball B is thrown vertically down with an initial velocity 'u' at t = 2 s. After a certain time, both balls meet 100 m above the ground. Find the value of 'u' in ms$$-$$1. [use g = 10 ms$$-$$2] :
