A copper wire of 3m and 1mm diameter is subjected to an extension of 5kg. calculate the elongation produced in the wire of Young modulus of elasticity of copper 120GPa.
what is the force required for a steel wire to double it length when it's area cross-section is 1 square cm and Young modulus is 200GPa as the length of the wire is double the change in length is equal to the original length.
In the laboratory, you attach a 300g mass to a spring of negligible mass and let it start to oscillate. The elapsed time from when the mass first moves through the equilibrium position to the second time it moves through that point is 2s. Find the force constant of the spring.
A ball on the ground is shot straight up and it reaches a maximum height of 25 m/s. (a) What was the ball’s initial velocity? (b) After reaching its maximum height, how long will the ball take before it lands again? (c) What is the ball’s speed just before it hits the ground?
A car moving at 30 m/s uniformly slows down to a speed of 10 m/s in a time of 6 seconds. Determine the acceleration of the car.
An object moving with uniformly accelerated motion moves in a straight line. Its initial velocity is 10 m/s and it travels at total distance of 700 m in 30 s. Compute the object’s (a) acceleration and (b) final velocity.
A cat moves from its resting spot under a tree to a nearby building to shelter from the rain. If it took 5 seconds for the cat to travel and the displacement of the tree to the building is 167 meters NW, what was its average velocity?
Differentiate between vernier calipers and mircometer screw gauage?
