Answer:
Explanation:
spring constant k = 425 N/m
a ) At the point of equilibrium
restoring force = frictional force
= kx = 10 N
425 x = 10
x = 2.35 cm
b )
Work done by frictional force
= -10 x 2.35 x 10⁻² x 2 J ( Distance is twice of 2.35 cm )
= - 0.47 J
= Kinetic energy remaining with the cookie as it slides back through the position where the spring is unstretched .
= 425 - 0.47
= 424.53 J
=

Each wheel has moment of inertia 
Linear speed speed 
angular speed of tire 
moment of inertia of motorcycle 
Initial moment of inertia 
Due to absence of external Torque we can Conserve Angular Moment of inertia
Answer:
GPE = 199.92 Joules
Work = 199.92 Joules
Explanation:
A 5.1 kg beer cub weighs 49.98N
Mg = F
g = F/M
g = 49.98/5.1
g = 9.8 m/s²
GPE = mgh
GPE = 5.1 * 9.8 * 4
GPE = 199.92 Joules
The work done by the mother is equal to the GPE , because
Force*distance = work
Force = 49.98N
Distance = 4m
Work = 199.92 Joules
