Answer:
1250N
Explanation:
Th force applied by the engine of this race car can be calculated using the formula: F = m × a
Where, F= force in Newtons (N)
m = mass in kilograms
a= acceleration in m/s^2
The mass of the race car is known (180kg). To find the acceleration (a), we divide the speed or velocity by the time taken i.e. a = v/t
Hence, a = 125/18
a = 6.9444m/s^2.
We can then find the force (F) by saying F= 180 × 6.944444
F = 1250Newtons.
