Yes, you need to convert unless the question specifically requires km/h.
Answer:
0.43 s
Explanation:
speed (s) = 95 mi/h = 95 x 1600/3600 = 42.5 m/s (converting to m/s)
distance (d) = 60 ft 6 inches = (60 x 0.3048) + (6 x 0.025) = 18.44 m (converting to meters)
speed = distance / time
time = distance / speed = 18.44 / 42.5 = 0.43 s
Answer:
The slope of a distance-time graph indicates the rate of change of distance and it is termed as speed.

Answer:
so kinetic energy of the drum is half the kinetic energy of the particle
Explanation:
Here we know that the particle is connected with the drum through a string
So here we can say that velocity of the particle is same as the tangential velocity of the drum as the particle is connected with the string which is wounded on the drum
So here we can say
now kinetic energy of the particle is given as
at the same time the rotational kinetic energy of the drum is given as
so kinetic energy of the drum is half the kinetic energy of the particle
Answer:
The energy stored in a body due to either it's position or change in shape is called gravitational potential energy.
