Answer:
-750N
Explanation:
Given :
Mass of the cycle = 15kg
Initial velocity of the cycle = 10m/s
Distance travelled = 10m
Final velocity of the cycle = 0m/s
To Find :
Force = ?
Solution :
Here F is force applied
m is the mass of the object
a is the acceleration
Acceleration is not given,so let’s find it’s acceleration.
According to the third equation of motion
Here v is the final velocity.
u is the initial velocity
a is the acceleration
Thus force,
Therefore,the force of friction between the road and the cycle is -750N
