Upon comparison, it is evident that the student with the highest percent error is A. Student 4, who measured 9.61 m/s². Four students recorded the acceleration of gravity, with the accepted local value being 9.78 m/s². Now let's find out which student's measurement exhibited the greatest percent error.
A basketball player maintains a steady pace of 2.5 m/s while throwing a basketball vertically at 6.0 m/s. How far does the player advance before getting the ball back? Air resistance is negligible. I was unsure which formula to apply to this scenario. Is there any relevance to an angle? First, we determine the duration to reach peak height. The total time for the flight will be double the ascent duration. According to Newton's equations of motion: v = u + at. At the highest point, v = 0, where u is 6 m/s. Thus, the equation becomes 0 = 6 - 9.81t, leading us to t = 0.61 seconds. Therefore, the total flight time equals 1.22 seconds as the player runs towards the ball at a horizontal speed of 2.5 m/s. The distance traveled can be calculated using distance = speed × time, resulting in distance = 2.5 m/s * 1.22, yielding a final distance of 6.11m.
(6-16)/4.0=-2.5 m/s²
The car's acceleration is -2.5 m/s²
Answer:
v = 66.4 m/s
Explanation:
We know that the aircraft starts off moving at a speed of
now we have
in the Y direction, we can apply kinematic equations
as there is no acceleration along the x-axis, the velocity in this direction remains unchanged
thus yielding
Answer: small barrel gun
Explanation:
It is noted that short barrel guns have a higher muzzle velocity for bullets compared to longer barrel guns.
Acceleration is determined by the change in velocity with respect to time.
For short barrel guns, the bullet reaches its muzzle velocity more quickly, leading to greater acceleration than that of bullets from long barrel guns.
