Answer 1

Answer:

Explanation:

a. Line OA & BC = Uniformly accelerated motion

Line OA is with Positive Acceleration & Line BC is with negative Acceleration

b. Decrease in Velocity = 120 - 0 = 120 m/s, time taken = 10 - 6 = 4 Sec

$Acceleration = -\frac{120}{4} = -30m/s^2$

c. At AB part the object observes constant velocity

d. Change in velocity = 120 m/s, time taken 3 sec

$Acceleration = \frac{120}{3} = 40m/s^2$

$Force=Mass\times Acceleration = \frac{50}{1000}\times40 Newton = \frac{2000}{1000} Newton = 2 Newton$

e.

$Force=Mass\times Acceleration = \frac{50}{1000}\times30 Newton = \frac{1500}{1000} Newton = 1.5 Newton$
