a body moves from rest with a constant acceleration of 15 m/s² find

1. the speed at the end of 10 sec
2. the average speed for 10 sec interval
3. the distance covered in 10 sec from rest

Question

a body moves from rest with a constant acceleration of 15
m/s2 find

1 the speed at the end of 10 sec
2 the average speed for 10 sec interval
3 the distance covered in 10 sec from rest

Dear student,
Given a=15ms-2 and it starts from rest, so initial velocity,
u=0
1 The speed at the end of 10s
⇒v=u+at=0+15×10=150m/s
3 The distance travelled in 10s
⇒S=ut+12at2=0+12×15×10×10=750m
2 Average speed for 10 sec interval
Average speed=Total Distance Total Time=75010=75m/s
