Starting from rest, a 2.1x10^-4 kg flea springs straight upward. While the flea is pushing off from the ground, the ground exert

Rainbow [258]

Answer:

a) The flea's speed when it leaves the ground is $v=1.88m/s$

b) The flea move $18cm$ upward while it is pushing off

Explanation:

<u>Knwons</u>

Mass $m=2.1\times 10^{-4} kg$ , Work $W=3.7\times 10^{-4} J$ and Force $F=0.41N$

a) Here we are going to use $W=\frac{1}{2} mv^{2}$ , so $v=\sqrt{\frac{2W}{m} }= \sqrt{\frac{2(3.7\times 10^{-4} J)}{2.1\times 10^{-4} kg} }=1.88m/s$

a) Here we are going to use $W=mgh$ , so $h=\frac{W}{mg}= \frac{3.7\times 10^{-4} J}{(2.1\times 10^{-4} kg)(9.8m/s^{2})} =0,1797m$ or $18cm$ approx.

A 7.3 kg bowling ball would require how much force if you use a broom to

il63 [147K]

Answer:

0.219N

Explanation:

Given data

mass= 7.3kg

acceleration= 0.03m/s^2

We know that

F=ma

substitute

F= 7.3*0.03

F= 0.219N

Hence the applied force is 0.219N

marshall27 [118]

Answer:

A. The brakes used a coil system to convert the kinetic energy into potential energy stored in the brakes

Explanation:

Based on the law of conservation of energy, the brakes used a coil system to convert the kinetic energy into potential energy stored in the brakes.

The law of conservation of energy states that energy is neither created nor destroyed in a system but it is transformed from one form to another.

As the airplane slows down, the kinetic energy which is presented in the motion of the plane is gradually converted to potential energy.

The potential energy is the energy due to the position of a body.

A student solving a physics problem for the range of a projectile has obtained the expression

Alika [10]

Answer:

The range of the projectile is 66.7 meters.

Explanation:

The range of a projectile is given by the following expression as :

$R=\dfrac{v_o^2\ sin2\theta}{g}$ ..............(1)

$v_o=37.2\ m/s$

$\theta=14.1^{\circ}$

$g=9.8\ m/s^2$

The range can be calculated using equation (1). Putting the values of all parameters we get :

$R=\dfrac{(37.2)^2\ sin2(14.1)}{9.8}$

R = 66.7 meters

So, the range of the projectile is 66.7 meters. Hence, this is the required solution.
