Answer:
The acceleration of the car is 7.85 m/s²
Explanation:
Given;
vx(t)= (0.910m/s³)t², given time traveled by the car 't' = 5.0 s
⇒To determine the velocity for 5 seconds, we substitute in 5.0 s for t
vx(5)= (0.910m/s³)(5s)²
= (0.910m/s³)(25s²)
vx = 22.75 m/s
⇒To determine the acceleration of the car when vx=12.0m/s
Acceleration is change in velocity per unit time
when vx=12.0m/s, our new equation becomes; 12 = (0.910m/s³)t²
Solving for t: t² = 12/0.91
t² = 13.187
t = √13.187 = 3.63 s
Acceleration = Δv/Δt
Acceleration = 7.85 m/s²
Hello there!
The correct answer is true.
If you where to pile up 1,000 glucose units, you could make ONE starch unit.
Answer:
v = 36.05 m/s
Explanation:
It is given that,
Initial speed of the parachutist, u = 14.8 m/s
Altitude, h = 55.1 m
The acceleration due to gravity,
Let v is the speed of the shoe just before it hits the ground. The third equation of motion is given by :
v = 36.05 m/s
So, the speed of the show just before it hits the ground is 36.05 m/s. Hence, this is the required solution.
Ohms law means
a law stating that electric current is proportional to voltage and inversely proportional to resistance
Answer:
While lifting two object the machine needs the different momentum for different mass object.
Explanation:
- Momentum is the quantity of motion contained in an object. Usually it is measured by the product of mass and velocity.
- Momentum of first mass = 2 kg × 2 m/sec = 4 kg m/sec
- Momentum of second mass = 4 kg × 3 m/sec = 12 kg m/sec
- So the machine requires higher mass in motion for second object ( i.e. momentum) than the first one while lifting.
