5 The 100 kg stone shown in Fig a is originally at rest on the smooth horizontal surface If a towing force of 200 N acting at an angle of 45 is applied to the stone for 10 s determine the final velocity and the normal force which the surface exerts on the stone during this time interval a 200 N 45 6 If motor M exerts a force of F 10t 100 N on the cable where t is in seconds determine the velocity of the 25 kg crate when t 4 s The coefficients of static and kinetic friction between the crate and the plane are 0 3 and 0 25 respectively The crate is initially at rest M 7 The crate has a mass of 80 kg and is being towed by a chain which is always directed at 20 from the horizontal as shown Determine the crate s acceleration in t 2 s if the coefficient of static friction is us 0 4 the coefficient of kinetic friction is 0 3 and the towing force is P 90t N where t is in seconds
