Answer 1

Answer:

The motion of a body along a straight line is described by the equation x=+

4t2+2t + 5. Where x is in metre and t is in second. Find (a) average velocity

during the time interval from t=0 to t= 5 s.(b)velocity of body at t=7s (c)

acceleration at t= 7 s.

47 m/s, 215 m/s, 54 m/s2

36 m/s, 214 m/s, 49 m/s2

47 m/s, 205 m/s, 50 m/s2

27 m/s, 254 m/s, 45 m/s2
