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:
E) The average velocity of the car is 90.0 miles per hour in the direction of motion.
Explanation:
Given;
distance covered by the car, d = 90 miles
time taken, t = 60 minutes = 1 hour
The average velocity of the car is given by change in displacement per change in time;
V = Δd / Δt
Therefore, the average velocity of the car is 90.0 miles per hour in the direction of motion.
