Answer:
1716.75 J
Explanation:
<u>Step </u><u>1</u><u>:</u> First check what we are provided with. As per given question we have:
mass (m) = 70 kg, height (h) = 2.5 m and acceleration due to gravity (g) = 9.81 m/s².
<u>Step</u><u> </u><u>2</u><u>:</u> Check what we are asked to find out.
Work done = Change in Potential energy
The stuff required to solve this question is potential energy. Using the formula: P = mgh. Where P is Potential energy, m is mass, g is acceleration due to gravity and h is height.
<u>Step</u><u> </u><u>3</u><u>:</u> Substitute the known values in the above formula.
→ P = 70 × 2.5 × 9.81
→ P = 1716.75 J
Hence, the work done against the force of gravity is 1716.75 J.
The distance vs time graph of a faster moving object would have a greater slope than that of a slower moving one. The object would move a greater distance per unit time
Answer:
5 years
Explanation:
The insurances mandate states that every driver or owner of a car has to have an insurance at least covering third parties damages and hospital care, this is to prevent people from going broke because of a car accident, if you faile to have one they would make you have proof of financial responsability for a year, if ater that failing, you are caught again without insurance withint 5 years the proof of financial responsability increases to 5 years.
Answer:
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. ... So forces cause acceleration.
1. Displacement = 50 m North. Distance = 150m
Displacement is a vector. Distance is a scalar.
2. Displacement is 100 miles East.
