A particle of mass `2 kg` moving with a velocity of `3 m//s` is acted upon by a force which changes its direction of motion by an angle of `90^(@)` without changing its speed. What is the magnitude of impulse experienced by the particle?

A particle moving with a speed v changes direction by an angle theta , without change in speed.

A particle moving with a speed v changes direction by an angle theta , without change in speed.

A particle moving with velocity V changes its direction of motion by an angle theta without change in speed. Which of the following Statement is not correct?

A particle of mass 120 g moving at speed of 750 cm/s is acted upon by a variable force opposite to its direction of motion. If the velocity of the particle becomes 250 cm/s along the direction of force, find the value of time 't' for which acted.

A particle of mass 70 g, moving at 50 cm/s , is acted upon by a variable force opposite to its direction of motion. The force F is shown as a function of time t (a) its speed will be 50 cm/s after the force stops acting (b) its direction of motion will reverse (c) its average acceleration will be 1 m//s^2 during the interval in which the force acts its average acceleration will be 10 m//s^2 during the interval in which the force acts

A particle of mass 120g moving at speed of 750cm/s is acted upon by a variable forrenpposite to its direction of motion as shown in figure. If the velocity of the particle becomes 250cm/s along the direction of force, fund the value of time't' for which force acted.

A particle of mass 1 kg is moving with a velocity of 200 m/s. An impulsive force of 4 s duration acts on the particle in a direction opposite to its motion. The force fluctuates a little bit around 40 N magnitude and then it dies out in next 4s showing small fluctuations. An oscilloscope records the force as shown. The two oscillating components in the graph are identical except that one is mirror image of the other. Find the magnitude of velocity of particle after the force stops acting.
