A pizza deliverer have 5 pizzas to deliver, in the following sequence A, B,C, D and E. The pizza company have a 45 min delivery policy, that means that the 5 pizzas should be deliver in that time.

Solve:
1) Calculate the total displacement of the deliverer.
NOTES:
You should use Pythagoreans theorem to find the distance between some points (A, B,C, D,E).
The units of the cartesian plane are km. (use 4 digits after the point in your calculations).
The deliverer start moving from 0 (that’s the direction of the pizza place) and finish in E (the last house).

the average speed is 24.57 km/hr

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:

formula.

example:

given values:

mass = 0.3 kg.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
