A ball is projected from a point at two different angles with the same speed U and land at the same point in both the cases

A ball is thrown at different angles with the same speed u and from the same points and it has same range in both the cases. If y_1 and y_2 be the heights attained in the two cases, then find the value of y_1 + y_2 .

Two balls are projected from the same point with such a speed that both reach the same point on ground at a distance of 19.6 sqrt(3) m from the point of projection. If one of the particles is projected at an angle of 30^(@) with the ground, then calculate the time of flight of the second ball.

A ball is projected from a point on the floor wilth a speed of 15 m/s at an angle of 60^0 with the horizontal. Will ilt hit a vertical wall 5 m away from the point of projection and perpendiculaer to the plane of projection without and perpendicular to the plane of projection without hitting the floor? will the answer differ if the wall is 22 m away?

A ball is thrown from a point with a speed v_0 at an angle of projection theta . From the same point and at the same instant, a person starts running with a constant speed v_0 /2 to catch the ball. Will the person be able to catch the ball ? If yes, what should be the angle of projection?

A ball is thrown from a point with a speed 'v^(0)' at an elevation angle of theta . From the same point and at the same instant , a person starts running with a constant speed ('v_(0)')/(2) to catch the ball . Will the person be able to catch the ball ? If yes, what should be the angle of projection theta ?

A particle at a height h from the ground is projected with an angle 30^@ from the horizontal, it strikes the ground making angle 45^@ with horizontal. It is again projected from the same point with the same speed but with an angle of 60^@ with horizontal. Find the angle it makes with the horizontal when it strikes the ground
