Question

A rocket-powered hockey puck has a thrust of 2.50 N and a total mass of 2.10 kg . It is released from rest on a frictionless table, 2.30 m from the edge of a 1.30 m drop. The front of the rocket is pointed directly toward the edge.

How far does the puck land from the base of the table?

Explanation / Answer

acceleration

a=F/m =2.5/2.1=1.19 m/s2

From

V2=Vo2+2ad

V2=0+2*1.19*2.3

V=2.34 m/s

From

Y=Yo+Vot-1(1/2)gt2

-1.3=0+0-(1/2)*9.8*t2

t=0.515 s

From

X=Vt+(1/2)at2 =2.34*0.515+(1/2)*1.19*0.5152

X=1.363 m
