Answer:
1.35208 m/s
Explanation:
Speed of the boat = 0.75 m/s
Distance between the shores = 100 m
Time = Distance / Speed

Time taken by the boat to get across is 133.33 seconds
Point C is 150 m from B
Speed = Distance / Time

Velocity of the water is 1.125 m/s
From Pythagoras theorem

So, the man's velocity relative to the shore is 1.35208 m/s

Answer:
Explanation:
Kinetic energy gained by alpha particle
= charge x potential difference
1/2 mv² = 3.2 x 10⁻¹⁹ x 3.45 x 10⁻³
.5 x 6.68 x 10⁻²⁷ V² = 11.04 x 10⁻²²
V² = 3.3 x 10⁵
V = 5.74 x 100
= 574 m / s
Mechanical energy is conserved in respect of A , C and D .
Part B
B , C, are unknown .
