Answer:

8.

(a) distance travelled by the car in first 2s,

d = 1/2*2*3 = 3m/s

(b) retardation = 3/1 = 3 m/s^2

Breaking force = m*a

= 1000*1 = 1000 N

9.

Resultant momentum,

= 5*2 - 2*3 = 10 - 6 = 4

10.

F1=F2

a2 = 5*a1

Then,

m1=5*m2

Ratio

m1/m2 = 5:1

11.

Speed = 36km/h = 36*1000/3600

= 10 m/s

Retardation = 10/2 = 5 m/s^2

Distance covered = 1/2*a*t*t

= 1/2*5*2*2

= 10 m

12. Final velocity

v = a*t = 9.8*8 = 78.4 m/s

Height

s = 1/2*a*t*t

= 1/2*9.8*8.8

= 313.6 m
