Answer:
14m/s
Explanation:
Given parameters:
Radius of the curve = 50m
Centripetal acceleration = 3.92m/s²
Unknown:
Speed needed to keep the car on the curve = ?
Solution:
The centripetal acceleration is the inwardly directly acceleration needed to keep a body along a curved path.
It is given as;
a =
a is the centripetal acceleration
v is the speed
r is the radius
Now insert the parameters and find v;
v² = ar
v² = 3.92 x 50 = 196
v = √196 = 14m/s

Answer:2.47
Explanation: did the math
A.The swimmer pushes the water
C. the walls force against the ball
Wavespeed = frequency x wavelength
= 14 x 9
= 126 mm/s
= 0.126 m/s
