Homework Statement
A body of mass 8.0 kg is initially at rest on a horizontal frictionless surface. A
force of 18 N acts on it and accelerates it to a final velocity of 12 m/s. Calculate
(a) the distance travelled,
(b) the work done by the force,
(c) the final KE of the body...
Yeah ..I just solve it thank so much
First we find the velocity from this formula v=at
Then we apply to find the time that it take to hit the ground which from this formula y=y0+v0y(t)+(1/2)gt^2
Finally we just multiply between the velocity from the answer 1 (6.5) and time 0.16
Is it right ??
Homework Statement
A girl shoves a book at rest on a table and it moves with an acceleration of 1.3 m/s . After 5 s, the book falls at the edge of the table. If the table height is 1.2 m, find the horizontal distance that it hit the floor. (ans: 3.22 m) ... How the answer would be 3.22...
