139.514 metres
Explanation:
Initial velocity of the truck = 6.6 m/s
Acceleration of the truck = 2.8 m/s^2
Time interval = 7.9 s
Therefore we use the formula,
s = ut + 1/2 at^2
*where s(the distance travelled)...u(the initial velocity)...t(the time period)
; s = 6.6(7.9) + 1/2 (2.8)(7.9)^2
; s = 52.14 + 87.374
The distance moved by the truck = 139.514m
Ответ:
Correct a₂ > a₁
Explanation:
Given:
Tony mass = m₁ = 50 kg
Sam mass = m₂ = 45 kg
According to Newton's second law, the formula for calculating force is:
F = m · a
In this case we have the same force for both
F = m₁ a₁ = m₂ a₂ => a₁ / a₂ = m₂ / m₁ = 45 / 50 = 9 / 10 = 0.9
a₁ = 0.9 a₂ => a₁ = 90% of a₂ => a₂ > a₁
a₂ > a₁
God is with you!!!
