What is the distance travelled by the tip of the seconds hand of a clock in 1 minute, if the length of the hand is 56 mm (use pi = (22)/(7))

In a simple Atwood machine, two unequal masses m_1 and m_2 are connected by string going over a clamped light smooth pulley . In a typical arrangement m_1=300g and m_2=600g . The system is released from rest. (a) Find the distance travelled by the first block in first two seconds. (b) Find the tension in the string. (c) Find the force exerted by clamp on the pulley.

From the veloicty time graph of a particle given in figure describe the motion of the particle qualitively int eh interval 0 to 4s. Find a. the distance travelled during first two seconds, b. during the time 2s to 4s, c. during the time 0 to 4s d. displacement during 0 to 4 s. e. acceleration at t=1/2 and f. acceleration at t=2s .

A man is standing between two vertical walls 680 m apart. He claps his hands and hears two distinct echoes after 0.9 se,conds and 1.1 second respectively. What is the speed of sound in the air? Given : Time of first echo, t_i = 0.9 s Time of second echo, t_2 = 1.1 s Distance between man and wall, d = 680 m To find : Speed of sound in air, V = ?

The distance x metres travelled by a vehicle in time t seconds after the breakes are applied is given by x=20 t-(5)/(3) t^(2) . Determine (i) the speed of the vehicle (in km /hr) at the instant the brakes are applied and (ii) the distance the car travelled before it stops.

A particle starts from rest with a constant acceleration. At a time t second, the speed is found to be 100 m/s and one second later the speed becomes 150 m/s. Find a. the acceleration and b. the distance travelled during the (t+1)^(th) second.

A particle moves along a horizontal line such that its position at any time t ge 0 is given by s(t)=t^(3)-6t^(2)+9t+1 , where s is measusred in metres and t in seconds ? (a) At what time the particle is at rest ? (3) Find the total distance travelled by the particle in the first 2 seconds.
