Here,
Average velocity during the first 3.46 s = 15.9/3.46 = 4.59
m/s
Average velocity during the next 0.293 s = -2.66/0.293 = -9.08
m/s
Average velocity during the final 3.68 s = 17.6/3.68 = 4.78
m/s
Now, the total average velocity = total displacement/ total
time
Total displacement = 15.9 – 2.66 + 17.6 = 30.84 m
Total time = 3.46 + 0.293 + 3.68 = 7.433 s
So, overall average velocity = 30.84/7.433 = 4.15 m/s

A rugby player passes the ball 7.25 m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 12.0 m/s, assuming that the smaller of the two possible angles was used? angle: ° What other angle gives the same range? other angle: ° For the pass using the smaller of the two angles, how long is the ball in the air? length...

A rugby player passes the ball 2.43 m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 5.3 m/s, assuming that the smaller of the two possible angles was used? What other angle gives the same range? (Why would it not be used?) How long did the pass (at the smaller angle) take?

While playing volleyball, a player sees the ball coming toward them with a velocity of 10 m/s. They hit the ball, and the ball rebounds at an angle of 30owith a velocity of 15 m/s. Find the impulse and find the average force applied to the ball during impact if the mass of the ball is 1 kg and the time of the impulse was 2 ms.

A ball is thrown straight up with an initial velocity of 19.6 m/s. Assume it experiences a constant acceleration of 9.8 m/s^2 down (due to gravity) throughout the entire motion. The motion we will consider is the one from the time it was thrown upward to the time it returns to its initial height, which will take a total of 4 seconds. (a) find an expression for the ball's acceleration as a function of time (b) sketch the acceleration as...

7) A baseball player releases a ball with an initial velocity of 35 m/s and it takes 2 seconds to reach max height. How high did the ball get? How long would it be before the other baseball player catches the ball? What is the release angle with respect to the vertical plane? How far into the field would the ball get?

A 110 kg running back carries the ball south at 8 m/s. A 130 kg linebacker runs to make the tackle going north at 5 m/s. In their collision, the linebacker wraps his arms around the runner and makes it an inelastic collision. How fast are they moving right after the collision (before they fall to the ground)? 3.

The OntarioTech rowing team is moving along at a steady speed of 17.86 m/s. The cox issues an order to increase the rate of speed of the boat and the boat uniformly accelerates to reach a final speed of 41.1 m/s. If the boat traveled a distance of 53 m before reaching the final velocity, what was the boat’s acceleration over that distance? An airplane accelerates down a runway at 13.7 m/s2 for 12.1 s until it finally lifts off...
