Question

5 A particle starts from rest with a uniform acceleration. Its
displacement after t sec is given in metres by the relation
x = 5 + 6t + 7+? Calculate the magnitude of its
(i) initial velocity
(ii) velocity at t=35
(iii) uniform acceleration (iv) displacement at t = 55.

Answer 1

Answer:

particle starts from origin with uniform acceleration. Its displacement after t seconds is given in meter by the relation x=2+5t+7t2. Calculate the magnitude of Initial velocity
