At maximum height the velocity component which becomes zero is

• Horizontal velocity component

• Vertical velocity component

• Both A and B

• None of these

To improve the jumping record, a long jumper should

• Jump at angle of 45⁰

• Jump at angle of 60⁰

• Jump as high as possible

• Jump at an angle of 30⁰

A ball is projected with a speed of 10 m/s. The angles of projection for which the range is 5.0 m are (g = 10 m/s²)

• 30⁰ , 60⁰

• 15⁰ , 75⁰

• 45⁰ , 45⁰

• 10⁰ , 80⁰

Two projectiles are fired from the same point with the same speed at angles of projection 60⁰ and 30⁰respectively. Which one of the following is true?

• Their time of flight will be same

• Their landing velocity will be same

• Their range will be same

• Their maximum height will be same

For a projectile, the ratio of maximum height reached to the square of flight time is (g = 10 m/s^-2)

• 5 : 2

• 5 : 4

• 5 : 1

• 10 : 1

The horizontal and the vertical components of the initial velocity of a projectile are 10 m/s and 20 m/s, respectively. The horizontal range of the projectile will be (g = 10 m/s^-2)

• 5m

• 10m

• 20m

• 40m
