A stone of a mass of 5.0 kg is attached to the end of a string as shown in the figure. It swung in a vertical circle of a radius R-2.0 m. If the string makes an angle of 37° with the vertical and the speed of the stone is v = 6 m/s, then what is the tension force (in N) in the string at this instant? (Assume.g-10 m/s²) 37° T QUESTION 11 A box with mass 5.00 kg starts sliding down a ramp (1.00 m long) which is inclined at an angle 30.0°as shown in Figure. Initially, the box was at rest and it experiences a frictional force of 7.00 N while sliding down until it reaches the bottom of the ramp. What is the speed (in m/s) of box at the bottom of the ramp? An object of mass 0.4 kg swung in a vertical circular path attached with a 0.5 m long string. If its speed is 6 m/s at the bottom of the circle, then what is the tension in the string (in N) there? (Assume. g-10 m/s²) R = 0.5 m QUESTION 9 A truck with a mass of 2000 kg is travelling with a velocity of 30 m/s. It slows down at a constant acceleration until it stops at a distance of 1000 m. What is the magnitude of the braking force (in N) acting on the truck? Three forces acting on an object of mass 4 kg, are given by, F1-(-2.0i+20) N. F2 (5.01-6.0) N and F3=(-15 ) N. If the object is initially at rest, what is its speed (in m/s) after 9.0 s? A block is sliding down on an inclined plane with an angle of 47°.

The block is connected by a string going over a masses and cyto second block of mass m2- 6.00 kg, as shown in the figure. What is the kinetic frictional coefficient y bebween the block and horizontal rough sta that keep the blocks to accelerate at 1.5 m/s²? (Assume, g -10.0 m/s²) m 13 A varying force.
