Answer:
m = 327.07 kg
Explanation:
Given that,
Kinetic energy of a motorcycle, E = 57800 J
Velocity of the motorcycle, v = 18.8 m/s
We need to find the mass of the motorcycle. The kinetic energy of an object is given by :

m is mass

So, the mass of the motorcycle is 327.07 kg.
Answer:
$364.29
Explanation:
given,
Packing of crates per month (u)= 800
annual carrying cost of 35 percent of the purchase price per crate.
Ordering cost(S) = $ 28
D = 800 x 12 = 9600 crates/year
H = 0.35 P
H = 0.35 x $10
H = $3.50/crate per yr.
Present Total cost
= 
= 1400 + 336
= $ 1,736



Total cost at EOQ
= 
= 685.86 + 685.85
= $ 1,371.71
the firm save annually in ordering and carrying costs by using the EOQ
= $ 1,736 - $ 1,371.71
= $364.29
Answer:


Explanation:
= Mass of first object
= Mass of second object
v = Speed of both objects
= Combined velocity
The ratio of final kinetic energy to initial kinetic energy will be

The ratio is 
As the linear momentum is conserved

Divide by
on both sides

The ratio of mass is 
Answer:
The answer is A
Explanation:
Being the force is acting upwards and displacement takes place horizontally
Kinetic energy (K.E) = 1/2 mass x velocity²
Momentum (P) = mass x velocity
K.E = 1/2 Pv
233 = 1/2 x 20.4 x v
v = 22.8 m/s
20.4 = 22.8m
m = 0.89 kg
