<span><span>When two people swing a jump rope, they can make it swing as a
single arc because they are connected
and it is the only way to swing the rope. Because if you swing it as as
two half-ropes arcing in opposite directions</span><span> it will not swing because force applied
counter acts the other.</span></span>
3ft is about 1m so approximately 3 nano seconds,
Answer:
Kinetic energy would increase by a factor of 4 where as momentum would increase by a factor of 2.
Explanation:
Kinetic Energy is given by 0.5*mass*velocity^2. Kinetic Energy is proportional to Velocity^2.
Momentum is given by mass*velocity. Momentum is proportional to Velocity.
If the velocity of an object is doubled, Kinetic energy would increase by a factor of 2^2 i.e 4 times. Momentum would increase by a factor of 2.
Answer:
72km/hr
Explanation:
Speed in Km is usually represented in hours. so if the car is in constant velocity, and if the car travels 36km in 30 min then it travels 72km in 1 hour.
so the speed of the car is 72km/hr
