Answer:
1.63
Explanation:
The equation would be used where:
g = acceleration due to gravity
G = universal gravitational constant (6.67408 ×
)
M = mass
R = radius.
assuming the values following both 10s of the mass and radius are their exponents, which is a little confusing, the values given would simply be substituted.
Anyone can correct me if I'm wrong.
Answer:
v = -24.5 m/s
Explanation:
Use conservation of momentum P = m*v. Unless there are external forces involved, total momentum must be conserved.
P: momentum
m: mass
v: velocity
1. calculate the total momentum before the collision:
2. the total momentum after the collision must not change:
3. after the collision the velocity of the car is the same as the velocity of the truck:
4. combining 2. and 3.:
5. this equation only has one unknown and can be solved for v:
