Answer: 18.9 m
Explanation:
i did the kinematic equation & found the answer.
Answer: Mass of car is 2660kg
Explanation:
Use equation for Kinetic ene)rgy :
Ek=(m*V²)/2
from this eqation you can get mass
m*V²=Ek*2
m=Ek*2/v²
Ek=5.32*100000J
V=20m/s
m=?
m=2*5.32*100000J/(20m/s)²
m=2660kg or 2.66t
Answer:
Convection. Convection is the transfer of heat energy in a fluid. ... As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere.

Hope this helps!
No velocity ws given? let's use
H= ½gt²
H= ½×10×3.8
H= 19m
