A drag racer starts from rest and accelerates at 7.4 m/s2. How far will he travel in 2.0 seconds?

3241004551 [841]

Using the kinematic equation below we can determine the distance traveled if t=2, a=7.4m/s^2. First we must determine the final velocity:

$v_{final}=v_{initial}+\frac{1}{2}at\\\\v_{final}=0+(7.4m/s^2)(2s)=34.8m/s$

Now we will determine the distance traveled:

$v_{final}^2=v_{initial}^2+2a \Delta x\\\\\Delta x = \frac{v_{final}^2}{2a} =\frac{(34.8)^2}{(2)(7.4)}=81.83 m$

Therefore, the drag racer traveled 81.83 meters in 2 seconds.

As soon as parachute of a falling soldier opens, how will the accleration change?

WITCHER [35]

Answer:

The acceleration will become zero

Explanation:

When the parachute of a falling soldier is opened the wide surface area decreases his velocity. This also translates to the drag force acting on the fallen soldier

The acceleration will become zero when the velocity of the fallen soldier is constant. This principle is the reason the parachute is used for safety reasons .

A turtle accelerates from a stop at 3m/s/s to the South for 8s. What is the turtle’s final velocity? Show your work and include

andrey2020 [161]

He's accelerating at 3 m/s² . That means his speed is increasing by 3 m/s every second.At the end of 8 seconds, his speed is (8 x 3 m/s) = 24 m/s .He's been moving south for the whole 8 seconds.So at the end of that time, his velocity is 24 m/s south .
