An athlete on a sled is moving with a speed of 3.0 m/s across a pond covered with ice. If the total mass of the sled-athlete system is 95.0 kg, what magnitude of the average force is required to bring the sled to rest in 15.0 s

Given Information:

Mass = m = 95 kg

Initial velocity = v₁ = 0 m/s

Final velocity = v₂ = 3 m/s

time = t = 15 seconds

Required Information:

magnitude of average force = ?

magnitude of average force = 19 N

Explanation:

From the Newton's second law of motion

F = ma

From the kinematics equations,

v₂ = v₁ + at

at = v₂ - v₁

a = (v₂ - v₁)/t

a = (3 - 0)/15

a = 0.2 m/s²

F = 95*0.2

F = 19 N

Therefore, the magnitude of the average force required to bring the sled to rest is 19 N.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
