What force is necessary to accelerates a 1250kg car at a rate of 40 m/s

F = 50000 N

Explanation:

The acceleration is rate of change of velocity of an object with respect to time.

Formula:

a = Δv/Δt

a = acceleration

Δv = change in velocity

Δt = change in time

Units:

The unit of acceleration is m. s⁻².

Acceleration can also be determine through following formula,

F = m * a

a = F/m

Given dа ta:

Mass of car = 1250 Kg

Acceleration = 40 m/s².

Force = ?

Solution:

F = m * a

F = 1250 Kg * 40 m/s²

Kg. m/s² = N

F = 50000 N
