Question

A point traversed half a circle of radius R = 160 cm during time interval τ = 10.0 s. Calculate the following quantities averaged over that time: 

(a) the mean velocity (v); 

(b) the modulus of the mean velocity vector |(v)I; 

(c) the modulus of the mean vector of the total acceleration I(w)I if the point moved with constant tangent acceleration.

Answer 1

(c) Let the point moves from i to f along the half circle (Fig.) and v₀ and v be the space at the point respectively.
