Answer:
decreases
Explanation:
The angular frequency of the mass is given by
where, k is the spring constant and m be the mass of the body which is doing oscillations.
if the mass of the body increases, so the value of angular frequency decreases, as the angular frequency is inversely proportional to the square root of the mass of the body.
Answer:
20 N exerts no torque about the pivot.
14 N exerts a counterclockwise torque of 14 * .3 = .42 N-m
6 exerts a clockwise torque of 6 * .7 = .42 N-m
The meter stick will not turn because there is no net torque on the meter stick.
Answer:
The the speed of the car is 26.91 m/s.
Explanation:
Given that,
distance d = 88 m
Kinetic friction = 0.42
We need to calculate the the speed of the car
Using the work-energy principle
work done = change in kinetic energy
Put the value into the formula
Hence, The the speed of the car is 26.91 m/s.
Answer:
The toy car
Explanation:
the real car is parked so yeah but maybe in some way technically the real car has more "momentum"
