Displacement is your answer :)
Answer:
9 kg
Explanation:
According to Newton's second law:
Given:
f = 18 N
a = 2 m/s^2
Substitute the given values in the formula.
Answer:
3.32 m/s
Explanation:
From the law of conservation of energy, the sum of mechanical and kinetic energy should be equal to the 10 J given. Potential energy is given by mgh where m is mass, g is acceleration due to gravity and h is the height. For this case, and l is string length, given as 2 m, \theta is given as 50 degrees. Kinetic energy is given by and it is this velocity that is unknown.
