Answer:
Ned will both swim and bicycle at every 24th day.
Step-by-step explanation:
It is given that Ned swim every sixth day and bicycle every eighth day.
For getting the days will he both swim and bicycle. We have to find Least Common Multiple(L.C.M) of 6 and 8.
6 = 2 × 3
8 = 2 × 2 × 2
⇒ LCM of (6 and 8) = 2 × 2 × 2 × 3 = 24
Hence, Ned will both swim and bicycle at every 24th day.
energy is always transformed from one form to another
energy is not created nor destroyed
so when a car starts moving the chemical potential energy of the car is converted to kinetic energy
kinetic energy is the energy that moving objects possess
kinetic energy formula is as follows
Kinetic energy = 1/2 mv²
where m - mass
v - velocity
substituting these values
K.E = 1/2 x 1350 kg x (12 m/s)²
= 1/2 x 1350 x 144 = 97200 J
the kinetic energy of the car is 97.2 kJ
Hello!
A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?
We have the following data:
m (mass) = 1350 kg
v (velocity) = 12 m/s
KE (kinetic Energy) = ? (in Joule)
Formula to calculate kinetic energy:
Solving:
