Find acceleration of an object if it is moving with uniform speed of 20m/s for 10seconds |
|
Answer» V=20U=20T=10A=v-u/t=20-20/10=0 U is 20 v is 0 and we know that A is v- u/t 0-20/10 is -2 we the answer is -2 And it is not written in the question whether the obiect started from rest i.e. its initial velocity is zero When an object moves with uniform velocity then its aacleration will be zero.Because its (v-u) will be zero. U-20 (u= initial velocity)V-0. (v=final velocity)T-10secWe know, a=v-u/tA=0-20/10A=-20/10A=-2(A=acceleration) |
