The two person of a body undergoing a uniformly accelerated motion are (10s, 10ms-1) and (30s, 50ms-1). On the velocity-time graph pf the body.
A
0.5ms-2
B
2.0ms-2
C
10.0ms-2
D
40.0ms-2
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Slope = a = \(\frac{\deltav}{\deltat}\)
= \(\frac{50 - 10}{30 - 10}\)
= 2.0ms-2
