In circular motion we know that there is two type of acceleration that Cheryl experience
1. Tangential acceleration
2. Centripetal acceleration
here given that
for centripetal acceleration we know that
now we know that both centripetal acceleration and tangential acceleration is perpendicular to each other
so total acceleration is vector sum of both and given as
so total acceleration is 8.54 m/s^2
Answer:
Option B
0.3 m/s2 South
Explanation:
Acceleration, 
where v and u are final and initial velocities respectively, t is the time taken
Substituting 14.1 m/s for v, 17.7 m/s for u and 12 s for t then
Since this is negative acceleration, it's direction is opposite hence 0.3 m/s2 South
Answer:
v = 225 m/s
Explanation:
Given,
The momentum of the spaceship, p = mv = 45,000 Kg m/s
The mass of the spaceship, m = 200 Kg
The velocity of the spaceship, v = ?
The relationship between the momentum, mass, and velocity is given by the formula
p = mv Kg m/s
Therefore,
v = p/m m/s
Substituting the values in the above equation
v = 45,000 Kg m/s / 200 Kg
= 225 m/s
Hence, the magnitude of velocity of the spaceship is, v = 225 m/s
Answer:
Yeah your right!! I don't watch Naruto. But you question should be about work. Not about a game.
Thxs for the free points though
