Parachute Dozen
help for physics?
The method through which the Mars Exploration Rover Spirit and Opportunity, landed on the surface of Mars in January 2004 was very expensive. The rover began its descent through the thin Martian atmosphere on a parachute until the amount reached approximately 16.7 m both a system of four air bags each with six lobes were inflated, retro rockets put to rest the trade, and replaced the Rover their parachutes. After a free fall to the surface, with an acceleration of 3.72 m / s 2, and bounce around a dozen times, deflated rovers their seats, stood up and went about their explorations. On the first bounce of the surface, Rover had an initial speed of 9.92 m / s at an angle of 75.0 degrees above the horizontal. (A) What is the maximum height of a Rover between the first and second was returned? (B) How far a rover rebounds Travel in a horizontal direction between the first and second?
It is necessary, the acceleration of gravity effect on the Martian surface, know that this question is 3.71 m / sec ^ 2 (The text says problem 3.72, we will ignore the difference) Now solve the velocity in the horizontal direction and vertical components, and calculate the time at max (9.92 sin 75) / 3.71 seconds .. The usual formula is the amount and the time has come back to earth to be twice the time at max. This time, multiplied by the horizontal component of velocity gives the distance.
