Answer:
915.69549 m
306.1968 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration = 3.25 m/s²
g = Acceleration due to gravity = 9.81 m/s²
Height is given by
Total distance the canister has to travel is 230+76.1968 = 306.1968 m
Time to reach the max height
Time taken to reach the ground is
Total time taken would be 3.9413+7.9 = 11.8413 seconds
The rocket is 685.69549+230 = 915.69549 m from the launchpad.
The total distance is 230+76.1968 = 306.1968 m
PART a)
Momentum is defined as product of mass and velocity
so here initial momentum is
given that
m = 0.3 kg
v = 18 m/s
towards East
Part b)
Since puck was initially at rest so here initial momentum must be ZERO
so here to find the force we can use
so here we have
time interval = 0.25 s
now from above equation
Part c)
Due to friction the puck lose its speed by 5 m/s
final speed = 18 - 5 = 13 m/s
mass = 0.3 kg
final momentum = (0.3)(13) = 3.9 kg m/s
now the impulse due to friction force is given as
Part d)
initial momentum of block will be ZERO as it is placed at rest
Initial momentum of the puck is given as
so total momentum before collision is given as
Part e)
since the system is isolated and there is no external force on it
So here momentum will remain conserved
so here we have
so final combined speed will be 2.6 m/s
Velocity is both speed and direction
Answer:
No, if a car is going faster. The RPM is obviously higher. If that is higher, you can burn through gas and energy much faster. A car going at 15mph would be cruising and wouldn't have to worry too much about burning our your vehicle.
