Concept explainers
(a)
To complete:The problem so that it can be solved for the given concept‘Acceleration’.
(a)
Explanation of Solution
Introduction:
The change of displacementwith respect to time is known as velocity.
The change of velocity with respect to time is called acceleration.
Explanation:
To calculate the acceleration of any moving body velocity of body and time of travel of body must be given in problem so the sentence can be completed like this
“Person A is playing basketball and throw the ball towards basket with speed 15m/s the ball bounces backfrom board with a speed of 16 m/s within 0.03 s. What is acceleration of the basketball during this interval of time?”
(b)
To complete:The problem so that it can be solved for the given concept ‘speed’.
(b)
Explanation of Solution
Introduction:
The average speed of object is ratio of total distance covered by the object with respect to time. It is scalar quantity.
Explanation: To calculate speed of any object distance travelled by the object within specific interval of time must be given.So, the sentence can be completed like this,
“Person A is playing basketball and moves in straight line 2m while dribbling the basketball within 5 s. Calculate average speed during the move?”

Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…arrow_forward
