Four projectile are projected with the same speed at angles 20°, 35°, 60° and 75º with the horizontal. The range will be the longest for the projectile whose angle of projection is. 35° 60° and 75º with the horizontal. The range will be the longest for the projectile whose angle of projection is. Four projectile [...]

A projectile has the same range R when the maximum height attained by it either H₁ or H₂. The R, H₁ and H2​ will be related as A projectile has the same range R when the maximum height attained by it either H₁ or H₂. The R H₁ and H2​ will be related as September [...]

A projectile thrown at an angle of 30 with the horizontal has a range R1​ and attains a maximum height h1​ . Another projectile thrown, with the same speed, at an angle 30 with the vertical, has a range R2​ and attains a maximum height h2​ . The relation between R1​ and R2​ is A [...]

A body is projected with kinetic energy K at an angle of 60° with the horizontal. Its kinetic energy at the highest point of its trajectory will be A body is projected with kinetic energy K at an angle of 60° with the horizontal. Its kinetic energy at the highest point of its trajectory will [...]

A body thrown along a frictionless inclined plane of angle of inclination 30 degrees covers a distance 40m along the plane. If the body is projected with the same speed at an angle of 30 degree with the ground, it will have a range of(take g=10m/s) A bomb is dropped from an aeroplane when it [...]

A cricketer can throw a ball to a maximum horizontal distance of 100 m. With the same effort, he throws the ball vertically upwards. The maximum height attained by the ball is : A cricketer can throw a ball to a maximum horizontal distance of 100 m. With the same effort he throws the ball [...]

A bomb is dropped from an aeroplane when it is at a height h directly above a target. If the aeroplane is moving horizontally at a speed v, the distance by which the bomb will miss the target is given by. A bomb is dropped from an aeroplane when it is at a height h [...]
