Four objects are situated along the y axis as follows: a 2.00 kg object is at +3.00 m, a 3.00- kg object is at +2.50 m, a 2.50-kg object is at the origin, and a 4.00-kg object is at -0.500 m. Where is the center of mass of these objects from the origin?

A fish swimming in a horizontal plane has velocity vi = (4.00i + 1.00j ) m/s at a point in the ocean where the position relative to a certain rock is ri = (10.0i - 4.00j) m. After the fish swims with constant acceleration for 20.0 s, its velocity is vf = (20.0i - 5.00j) m/s. (a) What are the components of the acceleration? (b) If the fish maintains constant acceleration, where is it at t =25.0 s?

A body of mass 2kg moving with velocity of 6m/s collides with a stationary object of mass 0.5kg. If the two bodies move together after the impact, calculate their common velocity.

A projectile is fired in such a way that its horizontal range is equal to its maximum height. What is the angle of projection?

If a bike is moving with a uniform velocity of 4m/s determine its acceleration after 30 seconds

A carousel is initially at rest, Ron is seating 3.0 m from the center. At an initial t=0, the carousel is given a constant angular acceleration of a=0.065 rad /s². At t=10.0 s, find the following quantities: (a) angular velocity of the carousel, (b) linear velocity of Ron, (c) his tangential acceleration, (d) his centripetal acceleration, and (e) his total acceleration.

1.             A fish swimming in a horizontal plane has velocity v_i = (4.00i + 1.00j ) m/s at a point in the ocean where the position relative to a certain rock is r_i = (10.0i - 4.00j) m. After the fish swims with constant acceleration for 20.0 s, its velocity is v_f = (20.0i - 5.00j) m/s.

(a) What are the components of the acceleration?

(b) If the fish maintains constant acceleration, where is it at t =25.0 s?
