What is the force on a body of mass 20 kg moving with an acceleration of 3 m/s2 ?

zubka84 [21]

Hey!!

Solution,

Mass(m)=20kg

Acceleration due to gravity(g)=3 m/s^2

Force=?

Now,

Force=m*g

 = 20*3

 = 60 Newton

The force is 60 Newton 

Hope it helps

Good luck on your assignment..

A child on a high dive has a mass of 40 kilograms. If the high dive is 10 meters in the air, what is the potential energy? GPE=m

saw5 [17]

Answer:

Ep = 3924 [J]

Explanation:

To calculate this value we must use the definition of potential energy which tells us that it is the product of mass by the acceleration of gravity by height.

$E_{p}=m*g*h\\$

where:

Ep = potential energy [J] (units of Joules)

m = mass = 40 [kg]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 10 [m]

$E_{p} =40*9.81*10\\E_{p} = 3924 [J]$

On the ignition switch, the ACC position provides power to electrical equipment including lights, wipers, warning lights and radio, without turning on the engine.

ACC is an Autonomous cruise control or adaptive cruise control is a system for road vehicles that automatically adjusts the vehicle speed (can increase or decrease the speed) to maintain a safe distance from vehicles ahead.

There are also many other names of Autonomous cruise control such as active cruise control, intelligent cruise control, or radar cruise control.
