Calculate the gravitational potential energy is a bicycle of mass 20kg and its rider of mass 50kg cycle to the top of a hill 120
1 answer:
Explanation:
Gravitational Potential Energy can be calculated with the following formula:
Where m is mass, g is Gravitational Field Strength, and h is height. GFS on Earth is always 9.81, the combined mass of the cyclist and the bicycle is 70, and the height is 120. Multiplying these values together, we get:
82,404J.

Explanation:
Displacement is the change in the position of an object.
Abigail runs a complete lap around the track, which is 400 meters. Even though she ran 400 meters, she has <u>no displacement.</u> If she starts and ends at the same spot, there is no change in position.
Gabi runs a 50 meter dash in a straight line. Gabi has <u>50 meters of displacement</u>. She runs in a straight line and is 50 meters away from where she began.
While Abigail ran the farther distance, <u>Gabi had the greater displacement.</u>
Answer:
Explanation:
From Newton's 2nd Law, we have . Using this, we can find the acceleration of the object:
.
Now that we've found the block's acceleration, we can use the following kinematics equation to find its final velocity after 2 seconds:
*Assumption: The block is initially at rest and has a initial velocity of zero. Otherwise, the question is unsolvable.
