Question

The velocity (v)-time (t) graph of motion of an object
is given below. If mass of the object is 5 kg, then
force acting on the object is
v(m/s)
70+--
20+
t(s)
5
(1) 250 N
(3) 50 N
(2) 125 N
(4) 500 N​

Answer 1

Answer:

50N

Explanation:

MASS = 5 KG

INETIAL VELOCITY = 20M/S

FINAL VELOCITY = 70M/S

ACCELERATION= V-U/T

70M/S-20M/S÷5sec

50m/s ÷ 5 = 10

therefore acceleration= 10 m/s^2

NOW ,F=MA

F= 5KG×10M/S^2

F= 50 N if it helped mark this answer brainliest
