CHAPTER 3 PROBLEM 79
Sin (48.5) = 0.750 / velocity along x - axis
velocity along x - axis = 0.998 = 1.0 m/s
CHAPTER 3 PROBLEM 82
Sin θ= 0.750 / 0.950
θ= 52.13
0
CHAPTER 4 PROBLEM 19
Height of the tower = 9m
So time of flight will be,
H = ½ gt
2

9 = ½ *9.81t
2

t = 1.35s
Now, Range is given as = 3.5m
From the basic formula of speed and time we have,
Distance = Speed * Time
3.5 = Speed*1.35
Speed = 2.59 m/s
So, launch speed will be = 2.59m/s
CHAPTER 4 PROBLEM 27
(a) Since the velocity of projection is same every object hence,
Larger the value of the angle smaller will be the horizontal component so,
uA < uB < uC
(b) Time of flight will depends on the length of the path tracked by the objects and sine component of the
velocity so,
Larger the sine component larger will be the time of flight of the projectile.
TC < TB < TA
CHAPTER 4 PROBLEM 37
(a)
Maximum initial...
