A 1000-kg car is moving along a straight road down a 30∘ slope at a constant speed of 20.0m/s. What is the net force acting on the car?

net force acting on the car is zero

Explanation:

given data

mass of car = 1000 kg

slope = 30°

constant speed = 20.0 m/s

to find out

net force acting on the car

solution

we know here that car is moving with given 20 m/s velocity so here net force acting on the car will be zero

as net force is express as

Force = mass * acceleration ... 1

and here acceleration is change of velocity per change in time

and here change in velocity is 0

so that net force will be zero

so net force acting on the car is zero
