Answer:
215mph
Explanation:
multiply 112milws by 2 and multiple that by seven, then divide it by two
Oil keeps the moving metal parts of an engine smoothly rubbing together through lubrication. Just like with other mechanical devices, energy can be lost due to friction caused by lack of proper lubrication. When an engine is running on old or insufficient oil, more friction and heat is produced between the rubbing moving parts. A decline in gas mileage follows this since the fuel takes more than usual to do the same task.
Answer:

Explanation:
given,
angle at which rock is thrown = 60°
rock lands at distance,d = 25 m
initial speed of rock, = ?
In horizontal direction
distance = speed x time
d = v₀ cos 60° t
25 = v₀ cos 60° t............(1)
now,
in vertical direction
displacement in vertical direction is zero
using equation of motion



putting the value of t in equation (1)

v


Hence, the initial speed of the rock is equal to 16.82 m/s
Answer: yeah it is reflection
