Naddika [18.5K]

Answer:

the rate of acceleration of the train is 4 m/s²

Explanation:

Given;

initial velocity of the train, u = 10 m/s

change in time of motion, dt = 5 s

final velocity of the train, v = 30 m/s

The rate of acceleration of the train is calculated as;

a = \frac{dv}{dt} = \frac{v-u}{dt} = \frac{30-10}{5} = \frac{20}{5} = 4 \ m/s^2

Therefore, the rate of acceleration of the train is 4 m/s²

Two water balloons of mass 0.35 kg collide and bounce off of each other
sladkih [1.3K]

Answer:

Option D

2 m/s East

Explanation:

From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum

Momentum, p=mv where m is the mass and v is the velocity

Since the masses are the same then

m(u_1+u_2)=m(v_1+v_2)  

Therefore

u_1+u_2=v_1+v_2

where v_1 and v_2 are final velocities of objects while u_1 and u_2 are the initial velocities respectively

Taking East direction as positive then West as negative and by substitution

2.5+-2.25=v_1-1.75

Therefore

v_1=2 m/s hence East since it's positive
