Question

A 3.5 kg object has a momentum of 26 kg-m/s. Calculate the speed of the object.

Answer 1

Answer:

7.43 m/s

Explanation:

p = mv

26 kg m/s = (3.5 kg) v

v = 7.43 m/s

Answer 2

Answer: 7.4 m/s

Explanation: Momentum is expressed in p = mv

We derive the equation to have  v = p / m

Substitute the values:

v= 26 kg m/s / 3.5 kg

  = 7.4 m/s
