Answer:
Explanation:
The gravitational potential energy gets transformed into translational and rotational kinetic energy, so we can write . Since
(the ball rolls without slipping) and for a solid sphere
, we have:
So our translational speed will be:
Answer:
90 m
Explanation:
Acceleration, where v and u are final and initial velocities respectively, t is the time taken
Substituting for a, 4 m/s for u and 10 s for t then
1*10=v-4
v=14 m/s
From kinematic equations
Making s the subject then
