Answer
a force between two bodies, molecules, particles, or the like, that attracts each to the other. Gravity is the force of attraction between two bodies that have mass.
Explanation:
Answer:
17.284 rad/s^2
Explanation:
F = 337 N
R = 0.398 m
M = 98 kg
let the angular acceleration is α
torque = I x α = F x R
Where I is the moment of inertia
I = 1/2 MR^2 = 0.5 x 98 x 0.398 x 0.398 = 7.76 kg m^2
So,
7.76 x α = 337 x 0.398
α = 17.284 rad/s^2
Jenny is traveling southward. In order to stop, she needs a northward acceleration.
A better way to say it:
Jenny is traveling southward in her bumper car, so the direction of her velocity is south. In order to reduce her velocity to zero, a velocity of equal magnitude but directed north must be added to it. Then the change in velocity is positive northward, and the change in velocity per unit time is acceleration.
