You're in an airplane that flies horizontally with speed 1100 km/h (300 m/s ) when an engine falls off. Neglecting air resistance, assume it takes 26 s for the engine to hit the ground.Find the height of airplane.

Answers

Answer:

The height of the airplane is 3312.4 meters.

Explanation:

Given that,

Speed of the airplane, v = 1100 km/h = 300 m/s

It takes 26 s for the engine to hit the ground. We need to find the height of the airplane. Using second equation of motion to find it as :

$h=ut+(1)/(2)at^2$

Here, u = 0 and a = g

$h=(1)/(2)gt^2\n\nh=(1)/(2)* 9.8* (26)^2\n\nh=3312.4\ m$

The height of the airplane is 3312.4 meters.

Li and Raj are playing football. They take turns trying to run past each other with the football. Li weighs 125 pound and Raj weighs 175 pounds. Li discovers that if he changes direction quickly when running, he can always dodge out of the way before Raj can tackle him.Why is Li able to avoid Raj’s tackle? Choose the best description.

Answers

Answer:

Li has less mass and therefore less inertia, so he can change his motion more easily than Raj.

Explanation:

Answer:

Li has less mass and therefore less inertia, so he can change his motion more easily than Raj.

1. A rifle with a longer barrel can fire bullets with a larger velocity than a rifle with a shorter barrel.

Answers

i dont believe so because thw longer the barrel the longer the bullet is inthe rifle shortening the force from the friction with the barrel so a rifle with a shorter barrel would be betterto use than one with a lomger barrel even though the longer barreled rifle may be more presice

A stone is dropped from a bridge and hits the pavement below in two seconds. What is the velocity of the stone when it hits the pavement?A. 0.20 m/s
B. 19.6 m/s
C. 4.9 m/s
D. 9.8 m/s

Answers

We have: a = v/t
Here, t = 2 s [ Given ]
a = 9.8 m/s² [constant value for earth system ]

Substitute their values into the expression:
9.8 = v/2
v = 9.8 × 2
v = 19.6 m/s

In short, Your Answer would be Option B

Hope this helps!

i just did the quiz and so the only 2 options that made logical sense would be B (19.6 m/s) or D (9.8 m/s) the reason someone could get confused between these two is because 19.6 divided by 2 is 9.8 m/s so for each second it will go down 9.8 m/s but since it wants to know the velocity it would be 19.6 m/s

hope this helps
