You have a bowling ball with a mass of 4kg. You throw it with an acceleration of 10 m/s/s. With how much force will it hit the p

Eddi Din [679]

Answer:

<h3>The answer is 40 N</h3>

Explanation:

The force acting on an object can be found by using the formula

<h3>force = mass × acceleration</h3>

From the question

mass = 4 kg

acceleration = 10 m/s²

So we have

force = 4 × 10

We have the final answer as

find the potential energy of an aircraft weighing 10000 bs at 5000 ft true altitude and 125 kts true air speed

Cloud [144]

Answer:

$U=5*10^7ft.Ib$

Explanation:

From the question we are told that

Weight $W= 10000bs$

Altitude $H=5000ft$

Speed $V=125kts\\1kts=0.514m/s\\V=125*0.514=>64.25m/s$

Generally the equation for Potential energy ids mathematically given as

$Potential\ Energy\ U=mgh$

$U=Wh$

$U=10000*5000$

$U=5*10^7ft.Ib$

A ball is dropped from mystery height and it accelerates at 8m/s/s and it takes .9 seconds to hit the ground what is the height

geniusboy [140]

Answer:

The height of the drop is 3.24 m.

Explanation:

As the ball is dropped from a mystery height and it takes 0.9 seconds to hit the ground with the acceleration of 8 m/s2. Then the velocity with which the ball is thrown can be determined as

$Velocity=Acceleration*Time$

As the acceleration is 8 m/s2 and time is 0.9 s. Then

$Velocity = 8*0.9=7.2 m/s$

So we know, the velocity u = 7.2 m/s , acceleration a = 8 m/s2 and time taken to reach the ground as t = 0.9 s. Thus, the height of the drop will be equal to the displacement of the ball from the top to the ground. Thus with the help of second equation of motion, we can determine the height as height will be equal to displacement (s).

$s=ut+\frac{1}{2}at^{2}$

Thus,

$s=(7.2*0)+(\frac{1}{2}*8*(0.9)^{2})=3.24 m$

Thus, the height of the drop will be 3.24 m.
