Let north and east be posetive
Y=20sin20
=6.840402867 south
X=20cos20
18.79385243 west
Net horizontal components=60+(-18.79)
=41.20614758m
Net vertical=-6.84040267
X^2=41.20614758^2+(-6.684040267)^2
√x^2 =√1744.73771m
x=41.77m

kondor19780726 [428]
The kinetic energy of the tomato is : 

K.E =  1/2 mv^2

K.E = 1/2 x 0.18 kg x 11 m/S^2

K.E = 0.99

Hope this helps

39. A dog runs on a waxed floor at an initial speed of 2 m/s. It slides to a stop with an
Sedbober [7]

Answer:

Explanation:

Use the one-dimensional equation

v_f=v_0+at where vf is the final velocity of the dog, v0 is the initial velocity of the dog, a is the acceleration of the dog, and t is the time it takesto reach that final velocity. For us:

0 = 2 + -.43t and

-2 = -.43t so

t = 4.7 seconds

Answer:

The Principle of Progression

(I searched it up since I never learned this)

Explanation:

The principle of progression states that a person should start slowly and increase exercise gradually. Since Mandy is just getting started on her exercise routine, she should begin with a few workouts over a large span of time, then work her way up so she can do more workouts in a shorter span of time.

A spinning turbine at an electrical plant produces energy that flows through wires to your house. The energy in the wires can be
Anna007 [38]

The spinning turbine converts mechanical energy into electrical energy that is converted into light energy used to light up the house.

<h3>What is law conservation of energy?</h3>

The law of conservation of energy states that energy can neither be created nor destroyed but can be transformed from one form to another.

The spinning turbine works on the principle of mechanical energy.

Thus, the spinning turbine converts mechanical energy into electrical energy that is converted into light energy used to light up the house.
