1250 N of force is required to accelerate a 250 kg motorcycle at a rate of 5 m/.
<u>Explanation:</u>
As per the second law of motion stated by Newton, the net unbalanced external force acting on any object is directly proportional to the product of mass and acceleration experienced by the object.
As here the object is given as motorcycle of mass 250 kg. Also the acceleration exhibited by the motorcycle is stated as 5 m/. So from the Newton's second law of motion,
Net force = Mass of the motorcycle× Acceleration of the motorcycle
Net force = 250 × 5 = 1250 N.
Thus, 1250 N of force is required to accelerate a 250 kg motorcycle at a rate of 5 m/.
Answer:
m = 27752.7 [kg]
Explanation:
To solve this problem we must first use the following equation of kinematics.
where:
Vf = final velocity = 240 [km/h]
Vo = initial velocity = 0
a = acceleration [m/s²]
t = time = 2 [s]
But first we must convert the speed from kilometers per hour to meters per second.
Now replacing:
Now using Newton's second law which is defined as the product of mass by acceleration we can determine the mass of the jet.
∑F = m*a
