The kinetic energy of a 204 kg motorcycle moves with a velocity of 6 m/s is 3672 joules (3672=0.5*204*6^2). This problem can be solved using the formula of an object's kinetic energy which is the energy of a motion. The formula of an object's kinetic energy is stated as KE = 0.5*m*v^2 where KE is the objects' kinetic energy amount, m is the object's mass, and v is the object's velocity<span>.</span>
The force applied is 47.3 N
Explanation:
First of all, we start by calculating the acceleration of Hailey, which is given by
where:
v = 3.5 m/s is the final velocity
u = 2 m/s is the initial velocity
t = 2 s is the time elapsed
Substituting, we find the acceleration:
Now we can find the force applied by using Newton's second law:
where
F is the force applied
m = 63 kg is the mass of Hailey+the skate
is the acceleration
Substituting, we find the force:
