Afactory conveyor belt rolls at 3 m/s. a mouse sees a piece of cheese directly across the belt and heads straight for the cheese at 4 m/s. what is the mouse's speed relative to the factory floor
a. 1m/s
b. 2m/s
c. 3m/s
d. 4m/s
e. 5m/s

mouse speed is 5 m/s

Explanation:

given data

belt roll b = 3 m/s

head straight h = 4 m/s

to find out

mouse speed s

solution

we will apply here pythagorean theorem

that is

s =   ...........................1

put here value in equation 1 as b = 3 and h = 4

so

s =

s =

s =

s =

s = 5

so mouse speed is 5 m/s

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.
