Answer:
60000J
Explanation:
Given parameters:
Mass of car = 1200kg
Speed = 10m/s
Unknown:
Kinetic energy = ?
Solution:
The kinetic energy is given as:
Kinetic energy = m v²
Now insert the parameters and solve;
m is the mass
v is the velocity
Kinetic energy = x 1200 x 10² = 60000J
What goes up must come down. Throwing something that eventually lands .
Answer:
C
Explanation:
I believe the answer is C.
100 m = 0.1 km
9.58 sec = 9.58/3600 = 0.00266 hr
Speed = 0.1/0.00266= 37.6 km/hr
