Answer:
The speed is 6.1m/s with an angle of 56.3 degrees north of east.
Explanation:
We meed to apply the Linear momentum theorem:
The magnitude of the velocity is given by:
and the angle:
Answer: (a) 5Joules
(b) 10m/s
(c) 1.0kgm/s
(d) 33.3N
Explanation:
(a) P E = mass * gravity * height
= 0.1*10*5 = 5Joules
(b) All PE is converted to KE
Therefore;
KE = 1/2 * mass * velocity^2
5 = 1/2 * 0.1 * v^2
V = sqrt(100)
v = 10m/s
(c) change in momentum = mass * velocity
= 0.1 * 10
= 1.0kgm/s
(d) impulse = change in momentum
Change in momentum = force * time
1.0 = force * 0.03
Force = 1.0/0.03
Force = 33.3N
Therefore, the force acting on the egg is 33.3N
The correct answer should be A. Misjudging others' abilities
Taking responsibility when you make a mistake and listening to your supervisor are a must in the adult world while saying thank you is not a mistake but rather a trait. Misjudging others' abilities can sometimes even be offensive and is common as a mistake.
Answer:
According to Newton's 2nd law
The force acting on a body produces acceleration in its direction which is directly propotional to the force but inversly propotinal to the mass of tbe body.
Explanation:
a = F/m
F = ma
Where( F) is force (m) is mass and (a) is acceleration.
