A toy car was moving whit a speed of 20 cm/s its speed became 50 m/s after traversing a distens of 1m. Calculate the acceleration of the car |
|
Answer» a t =3m/s 2
v=20m/s r=100m Centripetal ACCELERATION, a = r v 2
a c = 100 20×20 =4m/s 2
The RESULTANT acceleration, a= (a t ) 2 +(a c ) 2
a= (3) 2 +(4) 2
= 25 =5m/s 2
