D, releases a massive amount of energy as heat Hope this helps
T = ?
v1 = 0mph
v2 = 60mph
a = 8.7mph/s
Therefore, it takes 6.90 seconds for Jill to accelerate from 0 to 60 miles per hour.
Answer:
0,6
Explanation:
from the picture there are 10 dots. It means that the time needed to make these dot is
10/50 * 1 sec = 0.2 sec
the length (or we can say distance) of 10 dots are 12 cm. we must convert to meter so it become 0.12 m
v = d/t = 0.12/0.2 = 0.6 m/s
Force = mass*acceleration
acceleration = Force/mass
If you double the mass then acceleration will be halved in order for the equation to still equal.
New acceleration = Force/(2)mass
New acceleration = (1/2)* Force/mass------->if you compare this to original acceleration equation above it is 1/2
