You know that the formula for finding horizontal displacement is;
s=uₓt
s=(5 m/s)(3s)
s=15 m
Therefore, the ball travelled 15 m.
Hope I helped :)
Inertia is the property of all matter by which it tends to remain
in constant, uniform motion unless acted on by external force.
The answer is B) i am 100% positive
Answer:
160 m
Explanation:
distance covered in 1 s = 8 m
therefore, distance covered in 20 s = 8 * 20 m = 160 m
Q= calories
m = mass
c = specific heat
∆t = temperature difference
Also, Qin = Qout
(as in the amount of energy lost by the iron equals the energy gained by water. the water) so the calories lost is as stated in pict.
