A force of 7.01 N acts on a(n) 5.3 kg object
for 19.7 s. What is the object’s change in
momentum?
Answer in units of N · s.
B.)What is its change in velocity?
Answer in units of m/s.
To find the object's change in momentum, you can use the formula:
Change in momentum = force × time
Given that the force is 7.01 N and the time is 19.7 s, you can calculate the change in momentum using this formula.
Change in momentum = 7.01 N × 19.7 s
Change in momentum = 137.897 N · s
Therefore, the object's change in momentum is 137.897 N · s.
To find the object's change in velocity, you can use the formula:
Change in velocity = change in momentum / mass
Here, the mass of the object is given as 5.3 kg and the change in momentum is 137.897 N · s. Therefore, you can calculate the change in velocity using this formula.
Change in velocity = 137.897 N · s / 5.3 kg
Change in velocity = 26.01 m/s
Therefore, the object's change in velocity is 26.01 m/s.
