Solution to problem 13.3.20 from the collection of Kepe O.?. as follows:

Given: mass of the material point M, m = 1.6 kg; radius of the circle, R = 12 m; force acting on point F = 0.2t; time, t = 18 s; the angle between the velocity vector and the direction of the force, α = 25°.

You need to find the speed of a point at time t.

Answer:

1. Let's find the acceleration of the point. To do this, we use Newton's second law:

F = at,

where F is the force acting on the point, m is the mass of the point, a is its acceleration.

We substitute known values:

0,2t = 1,6a

a = 0,125t м/c²

1. Let's find the speed of the point at time t. To do this, we use the relationship between angular velocity and linear velocity when moving in a circle:

v = ωR,

where v is linear speed, ω is angular speed, R is the radius of the circle.

Angular velocity is defined as:

ω = v/R.

Thus, v = ωR = (α/180°)πR/t.

We substitute known values:

v = (25°/180°)π ⋅ 12 m/18 s = 3.38 m/s.

Answer: the speed of the point at time t = 18 s is 3.38 m/s.
