5.6 m/s
1.79 m/s
17.9 m/s
0.056 m/s User: Danny sails a boat downstream. The wind pushes the boat along at 21 km/hr. The current runs downstream at 15 km/hr. What is the actual velocity of the boat?
6.0 km/hr, downstream
1.4 km/hr, downstream
310 km/hr, downstream
36 km/hr, downstream

Weegy: 36 km/hr

A ride at an amusement park moves the riders in a circle at a rate of 6.0 m/s. If the radius of the ride is 9.0 meters, what is the acceleration of the ride?
4.0 m/s2
0.67 m/s2
0.075 m/s2
54 m/s2

Weegy: Formula a = v^2 / r
Here v = 6, r = 9, so a = 6^2 / 9 = 36/0 = 4.
Hence 4.0 m/s2 (More)
