Answer:
you divide distance traveled by the time it takes to travel that distance. average speed. If your speed changes from 10 km/h to 6 km/h, you have a(n) ... 400 km. Suppose that the average speed your dog can run is 3 m/s. ... she drives her scooter 7 kilometres north. She stops for lunch and then drives 5 kilometres south.
i rlly dunno lma.o
Explanation:
S = 1/2 g t^2
So t^2 = 2 S / g
So time = square root ( 300 / 9.80 )
Answer:
3.025 revolutions
Explanation:
To solve this question firstly we need to calculate the time t
Given the angular velocity and the angular acceleration
The time t = angular velocity/angular acceleration
Converting 50rpm to rad/s
= 50 × 2π /60
=1.67 rad/s
t = 1.67/0.46
t =3.63s
The wheel makes 50 revolutions in one minute
Therefore in 3.63s, it will make
3.63 × 50/60
= 181.5/60
=3.025 revolutions
Approximately 3 revolutions
