Answer:
a) momentum = mass × velocity
= 0.050 × 8 m / s
= 0.4 k g m/s
B) uniform velocity
c) a = u- v / t
= 0-20/5
= -20/5
= -4 m 2/s
d) 1/2 × Base × height × breadth× length
count the area of the triangle and rectangle below the velocity time graph . I don't know the correct measurements of height , breadth , base and length. so u use the above formula to find the area
