Answer:
Their velocity is 0m/s because the first box was only 10 kg and the second box was double the weight
Answer:
the curve inclination is increased so that a weight component helps keep the car on track
Explanation:
In the sledging competition these devices go at quite high speeds over 100 km/h, so when reaching the curves the friction force is not enough to keep the car on the track. For this reason, the curve inclination is increased so that a weight component helps keep the car on track.
In general we can solve Newton's second law for this case, with the condition of no friction, it is found that
V² = r g tan θ
Where V is the maximum velocity, r is the radius of the curve a, θ is the angle of the inclination
Answer:
False
Explanation:
Think about every warning on electrical products, which is 'DO NOT KEEP NEAR WATER'
