(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?”

One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as shown in the figure below. When the main leaf spring is compressed by distance yo, the helper spring engages and then helps to support any additional load. Suppose the leaf spring constant is 5.05 × 105 N/m, the helper spring constant is 3.50 x 105 N/m, and y = 0.500 m.

Some 1800 years ago Roman soldiers effectively used slings as deadly weapons. The length of these slings averaged about 81 cm and the lead shot that they used weighed about 30 grams. If in the wind up to a release, the shot rotated around the Roman slinger with a period of .15 seconds. Find the maximum acceleration of the shot before being released in m/s^2 and report it to two significant figures.arrow_forwardIn the movie Fast X, a 10100 kg round bomb is set rolling in Rome. The bomb gets up to 17.6 m/s. To try to stop the bomb, the protagonist Dom swings the counterweight of a crane, which has a mass of 354000 kg into the bomb at 3.61 m/s in the opposite direction. Directly after the collision the crane counterweight continues in the same direction it was going at 2.13 m/s.
