Answer:
2.7km
Explanation:
Two methods: Convert km/hour to km/minutes or convert 3/2 minutes to hours.
Then multiply time to get the distance of the car traveled.
83. Gravity is activity as a force on the cart.
84. The box has gathered kinetic energy and momentum and will continue going forward.
Answer:
Yes
Explanation:
Friction is a force that opposes relative motion between systems in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between systems and always in a direction that opposes motion or attempted motion of the systems relative to each other.
Using the precise speed of light in a vacuum (

), and your given distance of

, we can convert and cancel units to find the answer. The distance in m, using

, is

. Next, for the speed of light, we convert from s to min, using

, so we divide the speed of light by 60. Finally, dividing the distance between the Sun and Venus by the speed of light in km per min, we find that it is
6.405 min.
