Answer:
Explanation:
When we lift a ball with the hand the forces experienced by the ball is
Resultant of these forces gives acceleration to the ball
While your hand exerts a force on the ball, the ball will also exert a force of equal magnitude but opposite in direction to the force by hand.
All these forces is exerted on the ball, hand or on the earth.

Answer:
(a) Distance traveled = 75.3846 m
(b) Velocity of car at that instant will be 14 m/sec
Explanation:
We have given acceleration of the car 
Initial velocity of the cart u = 0 m/sec
(a) According to second equation of motion we know that 
So distance traveled by car 
As the truck is moving with constant speed
So distance traveled by truck 
As the truck overtakes the car
So 


So distance traveled 
(b) From second equation of motion we know that v = u+at
So v = 0+1.3×10.769 = 14 m /sec
Answer:
The relativistic speed of a particle is 
Explanation:
Given that,
Time = 6 sec
Force = 1
Mass of the particle 
We need to calculate the acceleration
Using formula of acceleration

Put the value into the formula


We need to calculate the velocity after 6 sec
Using equation of motion

Put the value


The velocity in term of c



Hence, The relativistic speed of a particle is
