Question

What is the mass of the cart with a constant net force of 200N is exerted to accelerate from rest to a velocity of 40m/s in 10 s.

Answer 1

Answer:

50kg

Step-by-step explanation:

Given:

Initial velocity- 0 m/s

Final velocity- 40. m/s

Time - 10s

Force - 200 N

Mass - ?

Acceleration- 40- 0 ÷ 10

= 40 ÷10

4 ms-2

Force = Mass × acceleration

200 = Mass X 4

Mass = 200 ÷ 4

= 50 kg
