A rocket is fired vertically with a speed of 5 km s^(-1) from the earth’s surface. How far from the earth does the rocket go before returning to the earth ? Mass of the earth = 6.0 x× 10^(24) kg, mean radius of the earth = 6.4 xx 10^(6) m , G = 6.67 xx 10^(-11) " N "m^(2) kg^(-2) .

A rocket is fired ‘vertically’ from the surface of mars with a speed of 2 km s^(–1) . If 20% of its initial energy is lost due to martian atmospheric resistance, how far will the rocket go from the surface of mars before returning to it ? Mass of mars = 6.4 ×x 10^(23) kg, radius of mars = 3395 km, G = 6.67 xx 10^(-11) N m^(2) Kg^(-2) .

A rocket is fired from the earth towards the sun. At what distance from the earth’s centre is the gravitational force on the rocket zero ? Mass of the sun = 2 xx 10^(30) kg. Mass of the earth = 6xx10^(24) kg. Neglect the effect of other planets etc. (orbittal radtus = 1.5 xx 10^(11) m ).

A crane has an arm length of 20 m inclined at 30° with the vertical. It carries a container of mass of 2 ton suspended from the top end of the arm. Find the torque produced by the gravitational force on the container about the point where the arm is fixed to the crane. [Given: 1 ton = 1000 kg, neglect the weight of the arm. g-10 m s^(-2)]

A rocket is moving at a speed of 200 m s^(-1) towards a stationary target. While moving, it emits a wave of frequency 1000 Hz. Some of the sound reaching the target gets reflected back to the rocket as an echo. Calculate (1) the frequency of the sound as detected by the target and (2) the frequency of the echo as detected by the rocket.

A 0.950 kg mass hangs vertically from a spring that he a spring constant of 8.50 N /m . The mass is set into vertical oscillations and after 600 s , you find tht the amplitude of the oscillation is 1/10 That of initial amplitude. What is the damping constant associated with this motion?

The US athlete Florence Griffith oyner won the 100 m spring gold medal at Seol Olympic 1988 setting a new Olympic record of 10.54s. Assume that she achieved her maximum speed in a very short time and then ran the race with that speed till she crossed the line. Take her mas ot be 50 kg. a. Calculate the kinetic energy of Griffith Joyner at her full speed. b. Assuming tht the track the wind etc. offered an average resistance of one tenth of her weight, cfalculate the work done by the resistsnce durng the run. c. What power Griffith Joyner had to exet ot maintain uniform speed?

A rocket is moving at a speed of 200m/s towards a stationary target. While moving, it emits a wave of frequency 1000Hz. Calculate the frequency of the sound as detected by the target. (Velocity of sound in air is 330m/s )
