​A football player weighing 110 kg and traveling at +6 m/s runs head on into another player who weighs 150 kg and is traveling a
Schach [20]

This is an <em>inelastic </em>collision. The equation for an inelastic collision is: m_{1}v_{1}_{i} + m_{2}v_{2}_{i} = (m_{1} + m_{2})v_{f}

(110)(6) + (150)(-4) = (110 + 150)(vf)

660 - 600 = 260vf

60 = 260vf

vf = 0.2308 m/s

They will travel in the positive direction, right, and their combined velocity will be 0.2308 m/s.

Hope this helps!! :)

serious [3.7K]
<span>1 pound is equal to .454 kilograms.
115 pounds equals
115 x .454 kilograms = 52.163 kg.

The total dose is equal to the dose per kilograms multiplied by the total mass in kilograms.

6.00mg/kg x 52.163kg = 312.978mg.

The total dose is 313.0 mg</span>

6.A truck drives to a rock quarry at a speed of 20 m/s. The truck takes on a load of
Karolina [17]

Explanation:

The kinetic energy is basically the energy possesses by virtue of a body's motion

1. The truck moving to the quarry

let the mass be x

and the velocity is given as 20m/s

we know that the kinetic energy is given as

KE=1/2mv^2

KE=1/2(x)*20^2

KE=1/2(x)400

KE=200x

2. The truck leaving to the quarry

let the mass be 2x

and the velocity is given as 20m/s

we know that the kinetic energy is given as

KE=1/2mv^2

KE=1/2(2x)*20^2

KE=1/2(2x)400

KE=400x

From the analysis the kinetic energy is a function of mass, doubling the mass doubles the kinetic energy
