Varvara68 [4.7K]

Answer:Best way i know to answer it is you do! However its not alot of mass to acually feel the force,

Explanation: Lets say you weigh 150 pounds here on earth. Then you go to the moon somehow, you'd weigh 22 pounds on the moon!  There for you standing near whoever, then theres around a 0.000000000012 force pulling on you, and you don't feel it because its such a small force being pulled.

If this answer helped please mark it as right <3 ty hope this helped!

A vehicle has an initial velocity of v0 when a tree falls on the roadway a distance xf in front of the vehicle. The driver has a
Korvikt [17]

Answer:

v^2=v_o^2-2\times a\times (v_o.t)

Explanation:

Given:

Initial velocity of the vehicle, v_o

distance between the car and the tree, x_f

time taken to respond to the situation, t

acceleration of the car after braking, a

Using equation of motion:

v^2=u^2+2a.s ..............(1)

where:

v= final velocity of the car when it hits the tree

u= initial velocity of the  car when the tree falls

a= acceleration after the brakes are applied

s= distance between the tree and the car after the brakes are applied.

s=v_o\times t

Now for this situation the eq. (1) becomes:

v^2=v_o^2-2\times a\times (v_o.t) (negative sign is for the deceleration after the brake is applied to the car.)

<span>A person expended 500 newtons to move a full wheelbarrow 30 meters how much work was done?

</span>In physics, a force is said to do work<span> if, when acting, there is a displacement of the point of application in the direction of the force. The work done would be calculated as follows:
