A snowmobile weighing 200 kg, developing a traction force of 800 N, increases its speed by 1.5

A snowmobile weighing 200 kg, developing a traction force of 800 N, increases its speed by 1.5 m / s for each second of acceleration. Find the friction force values

To find the value of the friction force acting on the snowmobile, we use Newton’s second law: m * a = F = Ft – Ftr, whence we express: Ftr = Ft – m * a.

Values of the variables: Fт – traction force of the snowmobile engine (Fт = 800 N); m is the mass of the snowmobile (m = 200 kg); a – acceleration (a = 1.5 m / s2).

Let’s perform the calculation: Ftr = Ft – m * a = 800 – 200 * 1.5 = 500 N.

Answer: The frictional force on the snowmobile is 500 N.
