A50kg i’ve skater goes around in a circle of radius 5.0m at a constant speed of 3.0m/s on a level ice rink. what is the magnitude of the horizontal force that the ice exerts on the skates?

90N

Explanation:

When resolving in a circular path we talk about Centripetal force

Mathematically;

Centripetal force (f) = mv^2 / r

Where m = mass

V = velocity

r = radius

Therefore;

50 x 3^2 / 5

= 90N

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

im sorry i dont know
