Motion in a Pla...

The range of a projectile fired at an angle of 15º is 50 m. If it is fired with the same speed at an angle of 45º. Its range will be

Two projectiles A and B are projected with angle of projection 30^o for the projectile A and 45^o for the projectile B. If R_A and R_B are the horizontal ranges for the two projectiles, then

A projectile is projected at an angle of 15º to the horizontal with some speed υ. If another projectile is projected with the same speed, then it must be projected at what angle with the horizontal so as to have the same range.

A man has two spheres A and B. He is standing at the top of a tower. He gently drops the sphere A vertically downwards and throws the sphere B horizontally at the same time. Neglecting the air friction, which of the following is the correct statement?

A body is projected horizontally with speed 20 m/s from top of a tower. What will be its speed nearly after 5 sec? Take g = 10 m/s²

A projectile thrown at an angle of 45º to the horizontal has a range of 19.6 m. Its velocity at the highest point is (g = 10 m/s²)

ball is thrown from the ground with a velocity of 20√3 m/s making an angle of 60º with the horizontal. The ball will be at a height of 40 m from the ground after a time t equal to (g = 10 ms^–2)
