The topic here is momentum.
When a collision is said to be elastic, it means that the colliding objects now travel at their own new, indivual and distinct velocities, often in different directions.
So we write that as,
(mass of football player x velocity of football player) + (mass of referee x velocity of referee) = (mass of football player x velocity of football player) + (mass of referee x velocity of referee)
(M × 8) + (80 × 0) = (M× 0) + (80 × 5)
8M = 400
M = 50 kg
im not 100 percent sure but i think its a
Answer: T = G - H/100
T= 12 - 12000/100 = 12 - 120 = - 105 degrees
Explanation:
T = G - H/100
T is temperature in centigrade degrees.
G is the temperature in centigrade degrees at ground level.
H is the height above ground level measured in meters.
assuming the temperature at ground level is 15 degrees centigrade, then G = 15.
the formula then becomes:
T = 15- H/100.
at ground level, H = 0 and the formula becomes 15 - 0/100 = 15 degrees centigrade.
at 100 meters, H = 100 and the formula becomes 15 - 100/100 = 15 - 1 = 14 degrees centigrade.
at 12 km above ground level, H = 12000 and the formula becomes 15 - 12000/ 100 = 15 - 120 = -105 degrees centigrade.
Answer:
The brakes don't grip the tires as securely as the water prevents a stable grip. The car will skid straight along the road as the tires don't have traction along a wet surface
