Answer:
moving slowly is the answer
The net force is -5 N so the box will move backwards
Answer:
The speed of the stone is 0.6138 c.
(B) is correct option.
Explanation:
Given that,
Mass of stone m= 0.6
Relativistic mass = 0.76
We need to calculate the speed
Using formula of rest mass
Put the value into the formula
Hence, The speed of the stone is 0.6138 c.
Answer:
Vf = 22.62 [m/s] in 2 seconds.
Explanation:
In order to solve this problem we must use the following kinematics equation
where:
Vf = final velocity [m/s]
Vi = initial velocity = 3 [m/s]
g = gravity acceleration = 9.81 [m/s^2]
t = time = 2 [s]
Vf = 3 + (9.81*2)
Vf = 22.62 [m/s]
