Answer:

The answer is A. an applied force results in movement of an object in the same direction as the applied force.

Explanation:

Work is the product of a force applied to a body and the displacement of the body in the direction of this force, that is, a force performs a work when there is a displacement of its point of application in the direction of that force. The work of the force on that body will be equivalent to the energy needed to move it.

Work occurs when an applied force results in movement of an object in the same direction as the applied force.

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.

A car travels initially at 24 m/s, until it enters the highway. If the car accelerates at 4 m/s^2 for a 96 meters, what is the c
marishachu [46]
  • initial velocity=u=24m/s
  • Acceleration=a=4m/s^2
  • Distance=s=96m
  • Final velocity=v

Using 3rd equation of kinematics

\boxed{\Large{\sf v^2-u^2=2as}}

\\ \Large\sf\longmapsto v^2=u^2+2as

\\ \Large\sf\longmapsto v^2=24^2+2(4)(96)

\\ \Large\sf\longmapsto v^2=576+768

\\ \Large\sf\longmapsto v^2=1344

\\ \Large\sf\longmapsto v=\sqrt{1344}

\\ \Large\sf\longmapsto v=36.6m/s

A tiger started running when it saw a deer running at uniform velocity 2m/s at 15m far from it ..if the tiger ran at acceleratio
Masteriza [31]
You need to set their position functions equal to one another and so for the time t when that is true. That is when the tiger and the deer are in the same place meaning the tiger catches the dear
Xdear= 2t+15 deer position function.
(I integrated the velocity function )
To get the Tigers position function you must integrate the acceleration twice. This becomes
Xtiger=t^2
Now t^2=2t+15
Time t is when the tiger catches the deer
t^2-2t-15=0
(t-5)(t+3)=0 factored
t=5s is the answer you use (t=-3 is a meaningless solution)

A stunt pilot weighing 0.70 kN performs a vertical circular dive of radius 0.80 km.At the bottom of the dive, the pilot has a sp
Yuliya22 [10]

Answer:

 Force plane exert on pilot  = 4270 N

Explanation:

first convert radius and speed to ms

using formula from force we know that

mass = weight/ gravity =  700 N/ 9.8N/kg=  71.4 kg

Fc=  N-mg

N= Fc+ mg                  As Fc = mv²/R

N= mv²/R + mg

taking m common

N= m( v²/R +g)

   = 71.4( (200)²/ 800 + 9.8 )

 Force  = 4270 N
