Answer:
h = 0.697 [m]
Explanation:
To solve this problem we must use the energy conservation theorem, where it tells us that kinetic energy is converted to potential energy or vice versa.
where:
Ekinet = kinetic energy [J]
Epot = potential energy [J]

Answer:
Tension in each cable = 175 N
Explanation:
Given:
Number of cables = 2
Weight of sign board(T) = 350 N
Find:
Tension in each cable
Computation:
We know that,
T1 = T2
So,
T1 + T2 = T
T1 + T2 = 350
T1 + T1 = 350
T1 = 175
Tension in each cable = 175 N
Answer:
m = 327.07 kg
Explanation:
Given that,
Kinetic energy of a motorcycle, E = 57800 J
Velocity of the motorcycle, v = 18.8 m/s
We need to find the mass of the motorcycle. The kinetic energy of an object is given by :
m is mass
So, the mass of the motorcycle is 327.07 kg.
