Horizontal velocity: 81.9 km/h
Vertical velocity: 57.4 km/h
Explanation:
We can solve this problem by resolving the velocity vector into its component along the horizontal and vertical direction.
The horizontal velocity of the stunt bike is given by:
where
v = 100 km/h is the magnitude of the velocity
is the angle of projection
Substituting, we find
The vertical velocity instead is given by
where
Substituting,

Answer:
Its internal energy decreases by 40 J.
Explanation:
The energy supplied to the metal block causes the temperature of the block to rise. Therefore,
Now, we will use this value of mC to find out the energy change of block:
It shows that when the temperature of the metal block falls by 10°C,
<u>Its internal energy decreases by 40 J.</u>
