Explanation:
As we know that
time = distance/speed
The time used for firs half of the trip was
(1 mi)(12 mi/hour) = 1/12 hours = 5 minutes
The last half of the trip will took 10 minutes, 1/6 hour.
Speed = distance/ time
(1 mil) = (1/6h) = 6 mil/h
so the speed for last half of the trip was = 6mph
the average speed was
(2mil)(1/4 hour) = 8 mil/hour
So the ling's average speed was 8mph.
Answer:
32.5 m/s
Explanation:
The total momentum must be conserved before and after the collision:
where
m_c = 300 kg is the mass of the car
m_t = 600 kg is the mass of the truck
u_c = 60 m/s is the initial velocity of the car
u_t = 10 m/s is the initial velocity of the truck
v_c = 15 m/s is the final velocity of the car
v_f is the final velocity of the truck
Solving for v_f, we find:
Heya!!
For calculate force, lets applicate second law of Newton:
<u>Δ Being Δ</u>
F = Force = ?
m = Mass = 50 kg
a = Aceleration = 7,2 m/s²
⇒ Let's replace according the formula:
⇒ Resolving
Result:
The force is <u>360 Netwons.</u>
Good Luck!!
