(B) Describes a parabola
(C) Describes an ellipse
(D) Describes a circle​

Answer 1

Answer:

(A) Describes a SHM is the answer

Answer 2

$ANSWER$

Given:

w=2rad/s

R=2m

t=π/2s

Angle travelled in time t, θ=wt=πrad

Magnitudeofvelocty=wR=4m/s

Change in Velocity ,△v=v

final

−v

initial

=4−(−4)=8m/s
