Answer:
17.11m
Explanation:
Weight of the block is ,
#Component of the weight acting normal to ramp is:
#Component of the weight acting parallel to the ramp and against block's motion :
Force of kinetic friction parallel to ramp and against block's motion:
We can now calculate deceleration up incline:
#The time,, of block's motion up incline is given as:
The block moves 17.11m up the incline.
Answer:
The magnitude of the horizontal displacement of the rock is 7.39 m/s.
Explanation:
Given that,
Initial speed = 11.5 m/s
Angle = 50.0
Height = 30.0 m
We need to calculate the horizontal displacement of the rock
Using formula of horizontal component
Put the value into the formula
Hence, The magnitude of the horizontal displacement of the rock is 7.39 m/s.

Answer:
16613 m/s
Explanation:
Given that
mass of the fly, m = 0.55 g = 0.55*10^-3 kg
Kinetic Energy of the fly, E = 7.6*10^4 J
Speed of the fly, v = ? m/s
We know that the Kinetic Energy is that energy that an object, in this case, the fly, possesses due to its motion.
The Kinetic Energy, KE of any object is represented by the formula
KE = 1/2 * m * v²
If we substitute the values in the relation, we have,
7.6*10^4 = 1/2 * 0.55*10^-3 * v²
v² = (15.2*10^4) / 0.55*10^-3
v² = 2.76*10^8
v = √2.76*10^8
v = 16613 m/s
Thus, the fly would need a speed of 16.6 km/s in order to have a Kinetic Energy of 7.6*10^4 J
Answer:
So heat required to raise the temperature of water is given as Q = 33472 J
Explanation:
As we know that the temperature of water is increased by 2 Degree C
So here we have heat gain by the water is given by the equation
Now we know that
m = 1000 g
s = 4.184 J/g C
Now plug in all data in above equation
