Question

a body of mass 10 kg starting from rest accelerates uniformly to a speed of 30 m/s in 10 seconds breaks are applied and the body stops in next 5 seconds distance travelled by body is
200
225
300
400​

Answer 1

Answer:

its not given in the options

Step-by-step explanation:

A body of mass 10kg starting from rest, accelerates uniformly to a speed of 30m//s in 10s. Brakes are applied and the body stops in next 5 seconds, (figure). Calculate the accelerating force and the stopping force. ∴ Retarding force F=ma=10(-6)=-60N.
