I think there would be an increase in force of friction
Gravitational potential energy=mass of object x gravitational field strength on earth(9.8 usually rounded to 10) x the height the object is held at
Therefore if two objects were held at the same height, the object with more mass(the heavier object) will fall faster because it's gravitational potential energy is greater than that of the lighter object
Answer:
The horizontal component of the velocity vector is;
vh = 34.4 ft/s
The vertical component of the velocity vector is;
vy = 49.1 ft/s
Explanation:
Given;
Velocity of football v = 60 ft/s
Angle of elevation ∅ = 55°
The horizontal component of the velocity vector is;
vh = vcos∅
Substituting the values;
vh = 60cos55°
vh = 34.41458618106 ft/s
vh = 34.4 ft/s
The vertical component of the velocity vector is;
vy = vsin∅
Substituting the values;
vy = 60sin55°
vy = 49.14912265733 ft/s
vy = 49.1 ft/s
Answer:
375 km
Explanation:
Using the equation, d = vt, we simply plug in the numbers:
v = 150 km/hr
t = 2.5 h
d = (150 km/hr)*(2.5 h)
d = 375 km
