Question 1

Which one of the following represents uniformly accelerated motion? a and b are constants and x is the distance described.

Question 2

Two bodies are thrown vertically upward, with the same initial velocity of 98 metre/sec but 4sec apart. How long after the first one is thrown will they meet?

Question 3

A rocket is fired vertically up from the ground. It moves upwards with a constant acceleration 10m/s² for 30 seconds after which the fuel is consumed. After what time from the instant of firing, the rocket will attain the maximum height? Take g = 10 m/s²

Question 4

A ball is thrown from the ground with a velocity of 80 ft/sec. Then the ball will be at a height of 96 feet above the ground after time -

Question 5

A stone is dropped from the top of the tower and travels 24.5m in the last second of its journey. The height of the tower is -

Question 6

A boat moves relative to water with a velocity which is 1/n times the river flow velocity. At what angle to the stream direction must be boat move to minimize drifting?

Question 7

The mass of spaceship is 1000 kg. It is to be launched from the earth’s surface out into free space. The value of ‘g’ and ‘R’ (radius of earth) are 10 m/s² and 6400 km respectively. The required energy for this work will be

Question 8

The escape velocity from a planet is V. If its mass and radius becomes four and two times respectively, then the escape velocity will become -

Question 9

A satellite revolving in a circular orbit at a height ‘h’ from the earth’s surface (radius of earth R; h << R). The minimum increase in its orbital velocity required, so that the satellite could escape from the earth’s gravitational field, is close to: (Neglect the effect of atmosphere.)

Question 10

The orbital velocity of an artificial satellite in a circular orbit just above the earth's surface is v. For a satellite orbiting at an altitude of half of the earth's radius, the orbital velocity is-
