Answer:
Explanation:
Given
initial speed(u)=5 m/s
Final speed(v)=4 m/s
Distance traveled=3 m
using equation of motion
after this its final velocity will be zero
s=5.33 m
Total distance=3+5.33=8.33 m
Thus he will not be able to win the game
Answer:
Explanation:
The equation that relates heat Q with the temperature change of a substance of mass <em>m </em>and specific heat <em>c </em>is
.
We want to calculate the final temperature <em>T, </em>so we have:
Which for our values means (in this case we do not need to convert the mass to Kg since <em>c</em> is given in g also and they cancel out, but we add to our temperature in
to have it in
as it must be):
As per kinematics equation we are given that
now we are given that
a = 2.55 m/s^2
now we need to find x
from above equation we have
so it will cover a distance of 93.2 m
