Question

a 5.00 kg ball accelerates at a rate of 2.00 m/s squared for 1.50 seconds. calculate the balls momentum after the acceleration

Answer 1

Answer:

  Momentum, P  = 15 kgm/s

Explanation:

We have equation of motion, v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

Initial velocity = 0 m/s, acceleration = 2 m/s², t = 1.50 s.

    v = 0 + 2 x 1.5 = 3 m/s

Momentum, P = mv, where m is the mass and v is the velocity.

Here    m = 5.00 kg

             v = 3 m/s

  Momentum, P = 5 x 3 = 15 kgm/s
