-- Sound energy. That's how you hear it explode.
-- Light energy. That's how you see it in the sky.
-- Heat energy. That's why you get burned if sparks fall on you.
-- Potential energy, as all the pieces fall to the ground.
These were all stored in it as chemical energy before it exploded.
B: Gravity.
The force of gravity will pull the car down the hill. The weight/mass of the car also helps this.
assuming north-south along the Y-axis and east-west along the X-axis
X = total X-displacement
from the graph , total displacement along X-direction is given as
X = 0 - 20 + 60 Cos45 + 0
X = 42.42 - 20
X = 22.42 m
Y = total Y- displacement
from the graph , total displacement along Y-direction is given as
Y = 40 + 0 + 60 Sin45 + 50
Y = 90 + 42.42
Y = 132.42 m
magnitude of the net displacement vector using Pythagorean theorem is given as
magnitude : Sqrt(X² + Y²) = Sqrt(22.42² + 132.42²) = 134.31 m
Direction : tan⁻¹(Y/X) = tan⁻¹(132.42/22.42) = 80.4 deg north of east
