Embibe Experts Solutions for Exercise 1: Exercise 4.1

The displacement $\left(x\right)-$ time $\left(t\right)$ curve of a particle is shown in figure. The external force acting on the particle is

The same horizontal force is applied to objects of different mass. Which of the following graphs illustrates the experimental results?

Four students perform an experiment by pulling an object horizontally across a frictionless table. They repeat the experiment on several other objects of different masses, always applying just enough force to produce the same acceleration. All of them, graph the results, individually. Which student's graph is correct?

Two cardboard boxes full of books are in contact with each other on a frictionless table. Box $H$ has twice the mass of box $G.$ If you push on box $G$ with a horizontal force $F,$ then box $H$ will experience a net force of

An Olympic diver dives off the high-ding platform. The magnitude of his momentum will be a maximum at point

What is the magnitude of the impulse of force shown in the following figure?

What is the impulse of force shown in the following figure?

A cricket player catches a ball of mass $100 \mathrm{g}$ moving with a speed of $25{ \mathrm{ms}}^{-1}.$ If the ball is caught in $0.1 \mathrm{s},$ the average force of the blow exerted on the hands of the player is
