Answer:
306.8264448 m
47.0016 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Distance traveled by car
Distance traveled by truck
In order to overtake both distances should be equal
The distance the car has to travel is 306.8264448 m
The speed of the car when it overtakes the truck is 47.0016 m/s
Answer:
t = 5.16 seconds.
Explanation:
The flight time can be found using the following equation:
Where:
t: is the time
g: is the gravity = 9.81 m/s²
y₀: is the initial height = 0
: is the final height = 5.50 m
: is the initial vertical velocity = v*sin(35)
v: is the speed = 46 m/s
By solving the above cuadratic equation we have:
t₁= 0.22 s and t₂= 5.16 s
We will take the solution equal to 5.16 seconds, since in 0.22 seconds (very short time) the ball is going up and in 5.16 seconds it landed on the green.
Therefore, 5.16 seconds have passed since the ball was hit until it landed.
I hope it helps you!
Answer:
The speed of the center of mass of the two carts is 0.103 m/s
Explanation:
It is given that,
Mass of the air track cart, m₁ = 350 g = 0.35 kg
Velocity of air track cart, v₁ = 1.25 m/s
Mass of cart, m₂ = 280 g = 0.28 kg
Velocity of cart, v₂ = -1.33 m/s (it is travelling in opposite direction)
We need to find the speed of the center of mass of the two carts. It is given by the following relation as :
Hence, this is the required solution.
