Answer:
216 J
Step-by-step explanation:
The kinetic energy is given by ...
KE = 1/2mv^2
KE = (1/2)(3 kg)(12 m/s)^2 = 216 kg·m²/s² = 216 J
The kinetic energy of the toy is 216 joules.
__
Its potential energy depends on its height.

Option D
The trip lasts for 
<em><u>Solution:</u></em>
<em><u>Mr Patel is planning to drive 325 miles</u></em>
Average speed is 65 mph
He will stop one hour for lunch and take a 15 min rest break
Let us first find the time taken
Thus he covers 325 miles in 5 hours
Also, given that, he will stop one hour for lunch and take a 15 min rest break
<em><u>Therefore, total time taken for trip is:</u></em>
Total time = 5 hours + 1 hour + 15 minutes
Total time = 6 hours 15 minutes
We know that,
1 hour = 60 minutes
Therefore,
Thus the trip lasts for
Given,
Diameter of the can = 3"
Height of the can = 7"
Looking at how the cans are arranged in the box, that is 4 x 5 (4 rows of cans [width] with 5 cans in each row [length])
The length of the box (L) = 5 cans multiplied by each can's diameter = 5 × 3" = 15"
The width of the box (W) = 4 cans multiplied by each can's diameter) = 4 × 3" = 12"
The height of the box (H) = 2 layers of cans = 2 cans multiplied by each can's height = 2 × 7" = 14"
Therefore, the volume of the box = Length (L) × Width (W) × Height (H) = 15" × 12" × 14" = 2520 inches³
Volume of the box = 2520 inches³
=====================================================
There is also an alternative method to calculate the volume of the box:
Consider each can. Although the can is cylindrical, each can would occupy the space required by a cuboid.
So, for each Cuboid space, the diameter of the can will be the length and width of the cuboid and the height of the can will be the height of the cuboid.
Therefore, for each can,
Length (L) = 3"
Width (W) = 3"
Height (H) = 7"
Volume occupied by one can (that is a cuboid) = L × W × H = 3" × 3" ×7" = 63 inches³
There are 40 such cans in total inside the box; therefore,
Volume of the box = 40 × 63 inches³ = 2520 inches³
