## Question number: 185

» Kinematics » Average Speed and Instantaneous Velocity

### Question

Savita throws a ball horizontally with a velocity of 8 m/s from the top of her building. The ball strikes to her brother Sudhir playing at 12 m away from the building. What is the height of the building?

### Choices

Choice (4) | Response | |
---|---|---|

a. | 11m | |

## Question number: 186

» Kinematics » Average Speed and Instantaneous Velocity

### Question

Choose the correct options

(1) A ball is dropped from the window of a moving train on horizontal rails, the path followed by the ball as observed by the observer on the ground is parabolic path.

(2) If T be the total time of flight of a current of water and H be the maximum height attained by it from the point of projection, then H/T will be (1/4) u sin 0

(u = projection velocity and 0 = projection angle)

(3) A hunter aims his gun and fires a bullet directly at a monkey on a tree. At the instant bullet leaves the gun, monkey drops, the bullet misses to hit the monkey.

(4) If a baseball player can throw a ball at maximum distance = d over a ground, the maximum vertical height to which he can throw it, will be d

(Ball have same initial speed in each case)

### Choices

Choice (4) | Response | |
---|---|---|

a. | 2 and 4 | |

b. | 1,2 and 3 | |

c. | 1 and 3 | |

d. | 1 and 2 |
